I doin't know about all that coded communication stuff, but anybody who paid attention and wasn't culturally predisposed to ignorance to the matter knew (& knows) that the Lennon/McCartney chord progressions were a subtly unique language.
OK, I plead cultural predisposition to ignorance (even though I used to be a big Beatles fan, and still like to hear them every now and again). What is special about the Beatles' chord progressions?

Yeah, me too. (Though I WASN'T a Beatles fan, after "My Bonnie".)

I couldn't get through that whole dissertation, but all the stuff about Beatles' chord progressions - I, IV and V going to relative and parallel majors and minors - is hardly unique. These are some of the most basic tools of harmonic composition.
Ok, relative to the Entire World Before Them, no, not especially unique. But in the realm of Post-Swing Era Popular Music, their cadences often fell "unusually", they'd land somewhere you'd not expect. Not usually really radical, just...not all that common. The little bit of the linked article that I was able to stay awake through goes to unnecessary, er....great lengths to say just about the same thing.
A few early examples:
"I Want To Hold Your Hand" - The first part of the A-section: I V7 vi III7 That III7 is setting up the relative minor ( vi ) as tonic, but now, the phrase goes back to the I. And forget about the bridge, that thing just kinda floats around. never really landing anywhere concrete.
"If I Fell" - Most people with reasonably harmonically acclimated ears can tell that this one plays beacoup games with false/deceptive resolutions.
"She Loves You" - At first, a I vi
iii (instead of the usual ii or IV) V cycle is sly enough, but when it comes time to say "she says she loves you", things start getting a little clever, going I vi ii7(b5) V - the ii7b5 "should" be found in a minor progression, not a major one. the symmetry here is nice too - in the first part of the phrase, the use of the iii chord, with its major 7th of the home key built into it, in the third bar adds extra "sunniness" to the feel, whereas the use of the ii7b5 in the second half - again the third chord in the sequence, but this time in the 6th bar instead of the 3rd, because the harmonic movement has suddenly slowed down, changes coming every two bars now, instead of every one bar as it started out - adds a very minor feel to an other wise typical major progression. So here you have a case of two four chord progressions in the same A section of the same song, and in each of them, the third chord adds accented harmonic "identity" to the progression, one major, one minor, the "irony" being that they both resolve major. And if you want to look at the form as A-B-Chorus instead of A1-A2-Chorus, then both the A & B sections are 8 bars in length, both use variants on the classic I-vi-ii-V progression, variating the 3rd chord of the sequence each time, only the A section uses its 8 bars to go through he sequence twice, but the B section only uses it once.
No, none of this was "new", but for a Rock/Pop band, it was a significant opening up of the "space" available in which to put your progressions. The symmetry became less inevitable, and the tonic chord no longer had to come about with redundant monotony. "Unpredictability" was now a desirable option, not something that the A&R man scratched out at every opportunity. You take all those Lennon/McCartney soundalike songs/records, what really seals the deal on them is the changes, and it usually involves some minor chord being used in an "unexpected" place and/or function. Jazz, the better Tin Pan Alley types, and of course, classical composers had all gotten to this before, this opening up of the playing field. But it was Lennon/McCartney who brought it to rock (with maybe a spirit in the dark nudge from Bacharach, maybe).
The list of examples could go on quite a long time, and even long after they all went solo, three of the four still showed an ability to craft those progressions that would throw you for a little loop here and there.
For those of you for whom this is all gobbledygook, sorry, but this is the language being used in the music. If you want a totally "non-technical" explanation, the best I can offer is "longer and/or different ways to get to the tonic chord".
