Using Worker 8 as a "stepping stone"

[-N-]

In the Nelveska Temple battles, for example, how are you supposed to use Worker 8 as a "stepping stone" to reach the top pillars? I've been testing it out in other battlefields and I can't get my characters to climb on top of him. Does anyone know the specifics?

edit: NM, just figured it out. W8 has a height of 3, so the panel that it's standing on is effectively 3+H, where H is the original height of the panel. A move-finder would then require a Jump of only 4 to get to the pillar at height 7.
