I would bet that there was somebody who insisted that one or the other of those loops was 2% faster on architecture X (for some value of X), and therefore demanded that it be allowed.
I would tend to assume that the int loop is marginally easier to branch-predict? But I'm somewhat skeptical that that was relevant on the hardware of the time...
