The "boundaries of remote work" means more "his coworkers only see him online, so his other online persona might be visible to his coworkers". If his coworkers or business associates find his online stand up, they might not be able to separate it from him because they only know him from online work, not in person.
Just about anything that "raises concerns about remote work" simply means one or more pro-office people have used it as an excuse to question remote work. Companies rarely question the boundaries of in person work when firing employees for actions caught while representing the company off hours (driving company vehicle, wearing company uniform).
