Evander's power doesn't kill people with kinetic energy, he just erases you(though if you have energy type power like Met you could resist it to some extent). Also Power doesn't "outrank" Destruction, the numbers don't indicate the strength and is not how all this works.
I'm not disagreeing necessarily, but I remember that in the scene where MC removed Jake's effect on Laurie's mind using his Memory abilities, MC was thinking something along the lines of "My power senses this power is of a higher order, though it recognizes I am much stronger than the user when they implanted this command".
This isn't definitive, there are definitely loopholes like saying it is of a higher order in specifically in that situation, so Authority is considered of a "higher order" than Memory when Memory is attempting to interfere in it's specialty, but it is a possibility.
Other possibilities include Authority being unique in that regard due to being, well, Authority, alongside Authority having a general type advantage over Memory.
