As the pinion gear turns the ring gear the forces push the entire differential towards the left. Normally the bearing on that side is capable of handling that leftward thrust.
I can not say with authority but suspect Ford added that thrust block in case that left hand bearing began to fail. It would keep those leftward forces from completely grenading the ring and pinion.
Ford used that same style thrust block on all their tractors with single reduction rear ends through at least 1983 that I know of.

In addition to that, it channels oil carried up by the ring gear to lube the bearing.
