Lots of ifs....

So, if the FO
says the right thing, he bears no responsibility for the improper operation of the aircraft? I don't think so. If the FO has an approved procedure or course of action available to him to deal with whatever the situation is and chooses not to exercise that option, then he's just as responsible. It's the Captain's show, but he's not going to get me killed, fired or violated.
After the "unstable" callout, there is supposed to be a go-around. The FOM gives no wiggle room. If the CA doesn't initiate a go-around, the next call-out is "Go around" by the FO. You can't "unsay" that and it must be complied with.
