Folks are free to do what they wish in their games... but the official Golarion canon is that Asmodeus significantly underestimated Baphomet (after, of course, Baphomet overestimated his own abilities).
It's far more interesting, in my opinion, for a deity as powerful and self-confident as Asmodeus to now and then make mistakes. He's not eager to force a new confrontation with Baphomet anytime soon, and isn't manipulating him... mostly because he doesn't see any advantage to doing so, but partially because he doesn't want to risk the chance, however small, that Baphomet might trick him again.
Baphomet's escape, in the grand scheme of things, is not much more than a minor annoyance and bit of shame to Asmodeus... but some day it could well come back to bite him!
I like this idea very much. It is more dramatic and powerful that from these kinds of “trifling“ issues beneath his notice, a god as powerful as Asmodeus shall fell.
