Okay, I was also of two minds while adding that line in the comment.
I had kept it because there are few places in the code where both
SubPlan and AlternativeSubPlan are handled together, so I thought the
person looking at this code should not wonder why we have not handled
AlternativeSubPlan. However, I think it is okay to remove it from
comment as there exist other places where only Subplan is handled and
we rely on expression tree walker for AlternativeSubPlans.
