I think hes saying that during the first quest, touching the Bubble causes you to not be able to draw your sword for a short period of time. But when he is playing the second quest, after touching one, he can't draw it out at all for the rest of the game, no matter if he leaves the room/dungeon.
I don't recall ever having this problem, so sorry that I can't help ya there. Really I only played the second quest maybe once through. Normally I just beat the normal game then quit when I go back to play it these days.
