Yes, each sub-device can have a different footprint and that footprint can change based on the currently selected personality.

The footprint field in DEVICE_INFO should always reflect the current personality. That means it will report a different footprint when the personality changes.

Most controllers will send a GET DEVICE_INFO after they change the personality to retrieve the information about the new personality.

As a side note: Changing personality can also change the number of sensors reported by a device (or sub-device).
