I would assume this is because wasting time (which is to the detriment of your opponent, and which he cannot control) in the first example is a not instrumental to achieving your goal. It is merely a side-effect.
“Thou shall not profit from wasting time”.
If playing optimally involves making decisions that make the game go longer (such as waiting to draw additional countermagic or whatever), so be it.
That said, I’m surprised Zvi said “match wp” here—I assume this is an oversight on his part. He should just have written “game wp”.
