it just is a quicker way of using the PP, so during raid, while your waiting for the battle to finish on one device, you use the 2nd, then the 3rd etc. So by then you've only skipped the battle sceens, its great for the Fairy Blessings cause instead of using only a portion of it, cause you have to wait for animation, and using PP and loading screens, you can use more of the item this way.
