But if you want to spend your free time watching replays of Warlight games you're not even in I guess I won't stop you
This can help you improve a lot. I am starting to analyse games between top players more and more, it helps you improve. Besides that he could`ve just been curious. Or maybe Lolo is Blowfly`s biggest fan and doesn`t want to miss a game he plays.
I'd say "could" instead of "can". If watching a ladder game with PC & QB like the one above will help you improve, something is not right. I'd rather be afraid that the "inefficacy" (I was searching for a non-insulting word) might rub off on you.
But I'm pretty sure you were referring to some other games.
Your second explanation does sound very likely though. :-) I now demand a Lolowut livestream in which he only discusses blowfly games!
