it is a lag/bad connection thing, that is what it was way back when. Your avatar doesn't switch to the proper state for the type of map due to missing info from the bad connection. Only thing I see different is that he has a space tray, the old bug had you with the right tray wrong avatar as I recall it.
this happened to me recently as well. as soon as i moved forward i was in space correctly, ive also lately been having issues where my armor will pickup space stats on login, then when im on ground i have to unequip then re equip my armor, making me wonder if this is a server issue ? i dont have any lag or a bad internet connection, but somehting is up.
