In the situation that's visible in the pictures the two zombie villagers don't want to walk up one block to get me. I've hit them, I've walked very near to them, until they hit me, but they don't want to follow anymore.

More generally no mobs/animals will climb steps in a north/south direction, they will actively seek a path that allows them to climb east/west and stall if they don't find one.
