You're completely right.
In these situations that's the most they can do.
He'd be an absolute idiot to try to take her, he'd more likely call them and attempt to defame me and trash me...
I'm hoping he never does either like your ex, but it scares me.
My friend had Ivy's on her ex-husband and their parents, it never stopped them from going to the school and breaching the order- nothing was ever done.
They seem to withhold those laws and only act on them against mothers that breach the orders in the slightest ways for their children's best interests, their wishes and safety.
