Are the handrails made like that for appearance or is their a

I'd imagine that the wide boards were to match and fully cover the
4x4s, but then were too wide for many hands to grab, so then the
narrower grip rail becomes necessary/advisable.

Make sense. The wide board would be OK to steady yourself, but not a
real grip if you needed it.
