Yeah no, I just replayed that scene, she doesn't mention anything like that, unless I got alternate dialogues or something, but maybe it's mentioned at some other point... who knows... but honestly it kinda makes sense she'd have switched while he went out to talk to ruth, maybe she secretly wanted to suck a "normie".
Maybe it just works with clones, although it wouldn't make sense why it didn't with the prisoner chick... who knows, I guess we'll see, but it could be a fun bit to realize he was actually getting sucked by the OG.
Oh and also, we never saw the "clone" disappear... that's another hint
