Normally, effects which deal crush to the opponent simply crush a Life Cloth and cannot check for win conditions, such as Yuzuki-Four, Fire of Nature being unable to win off her effect.

"Damage" refers to the kind of crush which does check for win condition - i.e., zero Life Cloths remaining. As a point of reference, think of it similar to SIGNI and LRIG attacks.

As for your question, this means that the opponent must have 0 Life Cloth at the time Diabride's second effect is activated in order to win the game.
