Yes, and for more than one reason unless they've tested them separately (can they though?). Here's two of them;

a) If performance is better, you then have to establish where exactly the improvement came from.

b) If one upgrade is a success, and the other is a step back (it happens), thereby offsetting the gain, what worked and what didn't?

Heady stuff!
