I never liked it either, because even though I felt safe/trusting that my T wouldn't hurt me physically, I'm no fool and I know humans can hurt anyone emotionally.... so that is always there. It felt safe but also anxious. I hated being stuck in the room. any time we were on walks, or did out of office sessions, or did sessions outside the room in any form, that's when I felt most safe, I felt safe with him generally to begin with but I didn't have the added anxious of feeling "trapped" in that small room.

I think it's just a line they use to get people to feel safe, even though it doesnt work for everyone
