Disconnecting the control rod in not essential; it just prevents having to actually increase the engine rpm during the test. I suspect that the instructions recommend disconnecting the lower end of the rod to avoid breaking the plastic lock on the upper end.
The VCV is a regulator; you can't test its function by without a constant vacuum being applied.
