On the North side of Terminal 5A are four stands, 501, 502, 503, and 505. Why is there no 504?

Image showing the North side of terminal 5A at Heathrow, stands 501, 502, 503, and 505 are shown.

Stand numbers at Heathrow correspond to the terminal and gate numbers. The first digit of the stand number is '5' for all terminal 5 stands, and the last 2 digits correspond to the gate number. So, the missing stands 504 and 510 would correspond to gates A4 and A10 respectively.

According to unverified (by me) reports on flyertalk.com, Gates A4 and A10 are exclusively "bus gates" where passengers board a bus rather than accessing via a jet bridge. So there is no corresponding stand next to the gate.

    $\begingroup$ What is the purpose of a bus gate on A4 and A10, is it in case an arrival expected at the A gates gets parked remotely for some reason? $\endgroup$

    $\begingroup$ @opr Such "airside transfers" are used at many airports. As for the logistical rationale... I'm not really sure! I think that would make a great standalone question if you care to post it. $\endgroup$
