I don't think the behavior of these two functions must be consistent
if a less consistent behavior makes more sense to the users.

C-t does what it does at the end of a buffer because that situation
frequently happens while typing (with people who type with both
hands).  Typing two words in the wrong order is much less frequent.

That's because it's not special: if point is at the beginning of the
buffer, the first word is still ``the word before or around point''.
