Dude, first of all, King already told him to just watch in the rec. room, which was the right answer as he clearly hadn't yet XP Second, you seem to have forgotten, but no, Leafa didn't specify anything, she tried tricking him that it was a different item she was using on him but he knew right away it was a one-way-working illusion, he just used admin hacks to make it 'visible for everyone' so she could know who she was trying to make him look like (And that's why Inoda and Asuna ended up being 'tricked', lol).
