I have no idea, but if I had to guess based on a couple of court cases that came up on youtube, the stalker has some carve out where they can go to work, but they have to take very inconvient ways to get there to minimize proximity to the victim.

Like another commenter said. Stalking victims already have to move to avoid their stalkers. This puts that responsibility on the offender rather than the victim. And a good relief for the victims
