with the concern about the abortion ban Amendment, that if passed in this legislative session (as the 2nd consecutive), would then allow the GOP to put it out as a referendum to change the state Constitution.

I think based on how those types of referendums have fared in other states, it would most likely fail but I think it's possible that those GOP women were sending a message to say - just leave it alone and keep the current state status quo restrictions in place, and not go any further. There is probably also a concern that failing any referendum, more and more restrictive and extremist legislation would have been put forward instead without some kind of check and balance. Mastriano is still in the state Senate and has already said he's pushing for full ban, no exceptions (although we know Shapiro would veto anything like that if it hits his desk).
