A roll pin is much stronger and spring steel to hold its tension shape. Cotter pins are soft. The pin is driven in with a drift. they compress as the go in. they are driven out with a drift, but often they are stuck and the steering box and coupler take a beating if you're not careful. Sometimes they get destroyed or go flying into the dirt when punched out. A cotter pin is a quick fix, but certainly.....NOT appropriate.
The roll pin fits against the rounded notch in the steering box splined shaft to locate the coupler on the splines for full engagement.

Pretty small hole, and unless the roll pin is press fit I guess they opted for a cotter pin to ensure it didn't fall out...I know I feel more comfortable knowing it's a cotter pin that can't fall out...

Found the source of the play in my steering, this car doesn't have a coupler as such, the shaft tapers flat and goes into the power steering gear. This is where it has the play. It looks like it is attached with a cotter pin, which I don't think is right. Stupid question but should there not be a bolt here instead of a cotter pin?
