Exactly right, more splines is more surface area, more contact, and load is spread over a larger area, that larger area makes the strainght.
I know it sounds backwards because the splines are so much bigger, but it is the contact surface that matters. (I am sure some engineer can say it better then me)
You hope you break more like this, and not into lots of parts, that take out your carrier, gears and bearings:
