The crew would have been expected to fly in accordance with the published procedure -- look at the plate I linked to a couple of pages back -- and in accordance with their SOPs.
Two further points; it was a localiser approach not an ILS, and their SOPs were unlikely to have had direction about how a mixed mode approach should be flown. Myself, I think I would probably have coupled to airspeed rather than V/S, but I can see why they would have coupled V/S -- to get a constant descent type approach.
