achievement's alternate ending secret dialogs ?

[gad24]

I think i noticed something strange: i was getting all the trophies on the campaign and once done i did the ending once again, but instead of cooper telling bt he is going nowhere or whatever, he said nothing... as if he knew something... and then bt activated protocol 3 and instead of being shocked and asking what the fluf is happening, jack said nothing... bt just said a remorseful: "goodbye Jack..." and while thrown in the air, Jack answered remorseful too: "bt..." did anybody noticed too or did i just dream everything? I just got my last achievement annihilation just before and completed the 50 achievements...

you should have 2 options just before being launched into the thing (forgot what it was called lol)

at the beginning of this video you can see the two options, and he chooses neither of them leading to this "third" choice
