Pretty much this.

On the way towards St Mary's we observe which buses we can see in front of us and which ones are going past in the opposite direction, that way we know whether we need to wait at St Marys or not.

We could easily go straight into Haymarket regardless of what we see but it isnt going to make any difference to passengers because if the bus before is still on the stand then either way we now still need to wait pretty much the same amount of time as we would have had we waited at St Marys, difference being that you now definitely cant get off why we wait at the top of the stands and in doing so could probably be blocking buses from reversing off or getting on to their own stand.

Thats why we wait

We change destination display at St Marys because they are supposed to be changed, in theory, while stationary, so cant do it when we are entering haymarket. Changing it when we get on stand will cause delays and confusion to passengers getting on the bus while they wait for the blind to update and if they dont know that mostly if it arrives as 309 it then goes out as 310 etc it just removes any issues
