I can't quite understand what they were checking though, as
everyone they stopped had already gone through the exit barrier
with their Oyster - and they were asking to scan them. They didn't
seem to care about those, like me, with paper tickets.

As the machine keep the used tickets, what proof of payment
do they expect you to have?

The original poster clearly said they were only checking Oyster cards,
not tickets. The proof of payment would be stored in the Oyster's
records.

The discussion had moved on to a question about the legality of
them demanding a ticket check from someone that they had seen
come out of an 'exit only' route (you seem to have snipped this bit
and returned only to the original question). As they would not
know if the person had an Oyster at this point, how could this be
a reasonable thing to do?
