It's not victim-blaming. She's not a victim, and he's not blaming her. It's
concern.
I get that the action itself is pretty much the same, but what matters is
intent. He doesn't want her harmed. It's like telling someone to be careful while climbing.
Phrasing is the key. He specifically mentioned her being "in danger". He's showing concern for someone he cares about, someone he thinks
might get hurt.
Edit: just to clarify, what
really changes the meaning is the timing. He's saying this
before anything happened, which still makes it kinda scummy but
not victim-blaming. He wants to
prevent something bad, not explain or lay blame.
