Didn't really understand why they would get passengers to go all the way out to T5B and then bus them over, as it led to a somewhat shambolic boarding process thanks to the mixture of pax on the busses.
its due to limited search equipment at A10 for the US selectees. However there is the equipment at every B and C gate.
