I am wary when Ts take it upon themselves to offer suggestions such as these when clients are not the ones to bring it up. It comes as making assumptions, of which I am not a big fan of anyway. Yes, T may be right but the potential for confusion or simply making wrong assumptions is simply too big. T could be wrong and potentially causing distress for clients. It's like Ts dump this on clients. And then what..?
I am sorry your T has caused distress, or stuckness. I don't think she should have said that..
