I don't know if it will be so much as caving, but more a case of taking this fig-leaf covering as a rationale to vote for this monstrosity ('...but they promised...').
Maybe Stupak has a degree of integrity - but I'm cynical when it comes to these Congresscritters - particularly the Dems. They'll say/do anything to get elected - but by the time they've made it to Washington D.C., they've sold out so many prior principles that they once held dear, that they are merely mouthpieces for whomever offers them the most power.
We'll see.
