There's a Lain-looking person with Lain's queue and another Lain-looking person in the background wearing Lain's bearsuit, and you insist it isn't Lain?
I guess he meant it in a "why is my Lain depicted like this? :(" way.
Lain is the one who decided that the best way to prevent problems with static was wearing only a camisole. So, if after being only in camisole she would still get any static on her, by her train of thought, the next step would be going full naked.
