Does drum-tracks need to be PHASED before editing?

Hey guys, I've edited all the drums for my band's album we're working on. Lots of stretching, cutting and moving has been done to the Bass-drum-, snare-, and tom-tracks. Very little to the Overheads.

Our guitar player is claiming that I should have PHASED the tracks before do ANY editing, and says the tracks needs to be re-edited completely from the start, doing the phasing as the first step.

Once again, overhead tracks are only very slighty edited, Room-mics barely at all.

Is it true you can't do the phasing now afterwards?

I will not edit the tracks myself again, there's a guy who will do this for relative cheap price 😁 but I want to know is there need for that. 🤔
