I think you have to take into account the possibility that Iovine likely heard the "album" in it's "finished" state from July (remember when they had the album-completion party?). So it's entirely possible that the subsequent work could account for both of these seemingly contradictory statements. I'm not saying it's probable, but I think there is a plausible explanation there.
It's a solid point but here's really what I'm getting at:
From roughly July/Aug 2008 (when they thought they had completed the album) working back to the Fez sessions and all, it's been nearly 2 years of recording. Whatever number that is, time in the studio, coupled with U2's track record of 2 years of recording for HTDAAB, another 18 months for ATYCLB, a solid 15 or more months for POP, all to produce about the same amount of songs. Around 15 +/-
I think U2's method of operations is to get to that number of 'album worthy' songs. Which would be 14-20 (whatever). All of this makes complete sense to me.
Take HTDAAB, delayed an entire year.
I can name exactly one original song that came out of that extra year.
Crumbs. The rest of them are either re-writes, re-recordings or leftovers from previous sessions. I reference the list from the white board on ATYCLB for one example.
So my point really is,
this is U2 we are talking about.
When Iovine said they need the two songs, it made complete sense to me, once again. They probably voted, and agreed on 8, 9 or 10 of the songs but felt they could hammer a few of the others back into shape, and in the meantime try some new stuff in this creative vein.
To assume that they would be somehow trying to 'up the ante' and re-doing all of those 'extras' for a double album doesn't make much sense to me, using U2's track record.
Let's say in July 2008 U2 had 18 songs ready to go, voted on by the U2 democracy. And let's say they decided they want 2 more songs to go with this double album instead of a single album.
Who here is going to make the argument that this makes any sense in light of U2' history, of not only struggling to agree on merely 11 or 12 album tracks, but getting that many quality tracks that they can agree on in such a short period?
I'm saying if U2 had 18 songs in July that were 'this' good, they'd pick the 12 best and release them in time for the prime sales period.
I think in light of all of this, I think the most simple explanation is the best.
They needed two more songs for a single album and decided ("what's the rush to get it right?"). If they were hurryng a double album it would be nothing
but rushing.
All that said, I would be very, very, very, very pleased with a double album.
I just don't think people should lose sight of who we are talking about here.
Think of the HTDAAB example again. An extra year for what, honestly?
