There's the sort of quantum uncertainty problem at play here: we observe in the credits sequence time moving forward, and yet we also return to the game just before that same sequence. So the question is: at what point does Flowey come and talk to "Chara" (assuming that it is indeed Chara that Flowey is talking to)?

Probably the only justification for using the same text is that Flowey is really talking to the player. The use of "Chara" could signify one of three things in this case: 1) Flowey is simply conflating the player with Chara. 2) Flowey is sending a signal that there may be something like Chara in the player. 3) The "see you later Chara" bit is an aside from the rest of the speech, and Flowey is not in fact referring to the player as "Chara" or claiming that Chara is the one who is in control of the timeline. At the very least Chara doesn't take over in this route until after the credits sequence, so there's no reason that Flowey would need to change his dialogue, because he has the exact same knowledge as he did in a normal TP ending.

If we take one of these readings, then those problems go away, at least mostly. There's still the "when" problem, but it seems as though the speech is meant to take place just shortly after the monsters have left, so not really enough time for Chara/Frisk to carry on their killing spree. Again, the game is sort of working in two time periods at once.

That's the best I can offer. I've generally been inclined to see the whole Flowey speech a sort of oversight in the universe, so this just further compounds the initial problem. I don't think there is a serious in-universe explanation.
