[PAR35]

“Not fully dispositive means that it is not dispositive” The two statements are congruent, although the first indicates that it is relevant, while the second is silent on that issue.

If the first remark had been "That case is quite helpful, but not fully dispositive", instead of what you typed, "That case is quite helpful, if not fully dispositive," I would not have seen your later remark as out of rig with your initial impression.

It's all good. Like I said, I'm totally indifferent as to your state of mind on the subject.
