Yes, they can't operate the website in USA so they'll operate it in Canada and Mexico. And yes, that's why they're targeting the stores and not the site, because the only thing they can do is prevent operations inside the country but they cannot block access to it.

Finally, of course technically Apple could only allow EU to do this, but much like their transition to USB-C it would be weird if they did that. ESPECIALLY since having Tik Tok on their phones would be a benefit to them, not a negative.

*Edit: Also I was defining free speech in my initial post, which you seem to agree with. I was not trying to define this abhorrent loophole of a bill that bans but doesn't ban because of 1A Tik Tok. And if you don't understand why the government trying to loophole out of the constitution is bad, well I have no words.
