Because it was at the corner and meant some ground traffic had to drive out on to the taxiway to get past. There was no 2-way traffic head of stand road at EDI between stands 4 and 6, IIRC. When the east side was redeveloped, two stands were made capable of housing large widebodies.
Oh, and the airbridge on 6/6A was a basket case, might have been replaced since I worked there.
But weights kick in again, that's another headache for GIP to tackle.
