Even if "Admin" was an admin on a wiki or two, they would not be on other wikis they'd visit, yet casual users might be misled into believing they were.

As noted, the specifics of global blocks and disablements are only discussed with the user in private. That username used wasn't impersonating staff. It was just a misleading username which tells them that it's a admin or staff, but it's not.
