My worry would be less about the gasket seal and more about tweaking the can....
That could be a possibility, however with a properly installed filter, ie., sealing gasket lubed, hand tightened to no more than 2/3-3/4 turn after gasket contact, damaging the can especially with a cap wrench very unlikely ime and imo.
As for removal not being mentioned by in the manufacturers that recommend 2 oci's, that's true. However, they also don't mention priming an oil filter which many also do before filter installation. So imo the same logic could be applied, it's likely more a feel good thing.
That said, as noted best practice says leave in place if running more than once.
