That was just for 1 sec and that's it. Nothing implies anything that you wanted here. Your example pretty much implied that Vegeta was just holding back.
The implication is there, after he powered down, when he hit Vegeta, he was surrprised that his power went down enough to where Vegeta can hit him. Nothing contradicts this point, his was confident in base, and smirked when he saw Vegeta turn ssj Blue and he clapped to mock him of his power. These pount don't contradict what is shown, and if so where. exactly. lol
