If you're changing terminals to T5 (whether airside or landside), you don't need to think about this until after you've arrived at T5.
If you're changing terminals from T5 (whether airside or landside), you also don't need to think about this because you have to leave T5 at the same point whichever gate you're starting from.
And any flight could theoretically depart from or arrive at any of T5A, T5B or T5C.
