The difference between VOR-A and VOR-B (as well as VOR-Z and VOR-Y) is that a runway may have a number of ways to enter the approach. So instead of calling it VOR-1 and VOR-2, which would be confusing, they use letters.

That is in itself correct, but not valid for the OP's question.
Circling approaches to an airfield is named with the type of approach and the letters of the alphabet, starting from in front (ie. NDB-A, VOR-C etc). The reason is as stated in the previous post, most often various directions.
Approaches that have different missed approach procedures are named as normal, and then appended a letter of the alphabet, starting from the last (ie. ILS-Z 24, LLZ-Y 19R). Normally the same procedure may have different missed approaches to cater for navaids being unserviceable.
So the picture shows the straight in VOR approach to runway 21, with the first (normal) variant of missed approach procedure.
