Wonderweiss did do exactly what he was supposed to (Yama did lose his powers exactly according to plan and as a result all the energy Wonderweiss absorbed made him into the bomb that took Yama out of the game) even though he was clearly a of one-shot-wonder and couldn't even beat a "powerless" Yamamoto in a pure fight. Whereas you are right about Yamamoto using his full power before Wonderweiss even showed up Yama would never have done that because they were in the world of the living so Aizen knew he could take his time and not have Wonderweiss there from the start or else Karakura Town and its surroundings might be annihilated
