No real need to factory reset an AP after upgrade. There is not a lot of security involved and the reboot following upgrade should take care of new wireless drivers if they were upgraded in the firmware. Even a device used as a router does not need to be reset following an upgrade most of the time.

Reset after upgrade is the best you can do.

Asus recommends restore to factory default after every firmware update. Part of user experience.

"It is recommended that you restore the router factory default settings after updating the firmware."

Sometimes the bits are not in the same place that the previous version used. Can give unexpected issues. Factory reset means you start with a clean memory. Restoring from a saved config file should not be used also. Manually config. Does not mean you can't get away with it for both. But if you get issues after upgrade of firmware, then these will be the first steps so you get back to a known good memory and config.
