I don't think it's the main reason, but as, for example Garrett Hack (I
believe) suggests, when using Bailey-like planes the push-hand
index-finger can be used to adjust the depth-control "on the fly".

But more practically, I think the issue is that for many people (myself
included) there is really only (comfortably) room on most planes for three
fingers in the tote. Given that, it's just much more comfortable and
natural --as well as probably safer-- to extend the index finger along the
side of the upper part of the iron than to place the pinky somewhere.
