I assume you are reffering to A21X?
Gate A21 can be used for narrowbody and widebody departures. Widebodys are lined up on a different line which is referred to as A21X so that it doesn't obstruct any other gates.
The X is purely for operational purposes... as long as you're at gate 21 you're good to go
