And what rule is it that makes this method of "top up" un-refundable if you
don't use it?

Auto top-up triggers whenever the balance falls below £5. Thus your
balance is always in the £5-£25 range, never below. The loophole I'm
suggesting is to add cash before each journey to keep it in the £5-£10
range, but what you can't ever do with a card with auto top-up enabled
is spend the last £5.

You can still have the card refunded of course, but then you have no
Oyster Card.

The topup triggers when you ENTER a station with your balance below
5GBP. So you should top you your card before every journey to 5.10 and
then the topup won't trigger. There are a handful of journeys where your
card balance can actually go negative if you plan it right (but the
deposit will be more than the negative balance)
