That can be justified because in the former Garnet only said this because Alexandrite is a very complex fusion and it can physically exaust the gems by the time they unfuse. Pearl likely said it in the latter episode because she really had no reason to fuse also she was quarreling with Amethyst at the time which probably highlighted her desire not to form Opal cause it's been implied before they used to fuse more often
 * Although it was said in "Fusion Cuisine" and "Giant Woman" that fusion is serious magic and should not be used for fun, Rose and Pearl seemed to have no problem with fusing to form Rainbow Quartz purely for the purpose of entertainment.
