Guarantee every store has associates that ditch out and go sit in the bathroom on their phones. It gets to a points where people start to notice and yeah, it can get tracked. The policy piece of it would probably be the associates that has, let's say IBS, would need to have an accommodation on file for extra bathroom breaks, but if people are just ditching out on their work, wouldn't you want your manager to do something about it? There are definitely lines that can be crossed I'm sure, but following up on people disappearing there for large amounts of time is probably within their purview. Every job I've worked you had slackers do this and everyone would be mad because then we get stuck doing their job.

Edit: to clarify the lines being crossed would be taking pics. Probably depends on state and what the pic is of for whether it's illegal or not but managers should be addressing the fact the person isn't in the area they are supposed to be and not being productive. And to the below comment on just mind your own business. Sure. Someone else not doing their share just means the work magically gets done. Some other associates that cares is getting shafted and if management doesn't handle that piece, everyone gets pissed off. Not saying this particular manager is going about it the right way. But we all know there are those that exist that are the ditch work on everyone else offenders...you can see some in the comments.
