So personal and friends and family are separate. In fact some launches staff can use their personal on preorder day. Back in the day when you had to order from within work they’d open the stores early for staff to go in and order. Now they can do it from home.
As for personal epp for others. Technically the rule is you have to be able to produce the device whenever asked for it. I think the idea is that proves you didn’t sell it off for profits. With that said, I’ve never heard of them really checking on this. Bigger issue is you only get one personal purchase a year, so often friends are lowest on the list behind the staff member themselves and then family after that.
