I do not think the processes have to be revalidated because of multiple locations. However, I will add that the quality team may have argued this if they saw that each location would impact the equipment in someway which may change the end results. That is the only way I see the quality team arguing this. If the location influences the end result, then yes the processes would need to be re-validated. I do not have any industry experience so my personal exposure to such cases is limited to none. I may be wrong but thats what I understand from the class notes.
