Okay, again thinking about it after your explanation, it appears
correct to me, but it was not apparent on the first read. I think
other alternatives could be (a) Evaluation of initplan OR (b)
Execution of initplan. I think it makes sense to add what you have
written or one of the alternatives suggested by me as you deem most
appropriate. I think one can always write a detailed explanation as a
separate patch.
