He's saying that if you save the LV3s and use them all at once, you can find a pattern to help you get what you are looking for. But if you just purify every one you get, the pattern would reset, keeping your odds around 10% for what you're looking for. For example, if you tried purifying two Armor LV3s five different times, you could quite possibly not get any high tier armors even though you purified ten LV3s. But if you purified all ten at once, you would have a 100% of getting a high tier armor twice, at the third and eighth or fifth and tenth.
