I've always wondered that, too.
I got banned at a "certain chain" of properties about 20 years ago, and they added a new one. I was wondering if I could go there without being arrested, as that new property was not named when I was trespassed (because it didn't exist). It also wasn't obvious that this property was one of theirs by its name, so I could always claim ignorance.
I decided I probably could, but I'm not sure what the law says.
I've since had the ban rescinded anyway, so today it's a non-issue.
