In the same way that "you kids aren't allowed to skate here, but maybe if you do it over there I could just turn around and not notice you" isn't a threat.

"you kids can't skate here" is the threat part.

That's just stretching the definition of "threat" beyond its normal meaning.

If I tell my kids "it's bedtime" is that a threat?

If they say "no" are you gonna let them stay up?

If not then it may not be a literal threat but it contains the implied threat

There is no reason to assume they said that and all the reason to assume they didn't say that.
