This has nothing to do with ortholinear movement. It's true in every
movement system known to man. Even with diagonal movement, there will
be many equally good movement paths between two locations. For example,
from aa01 to ab03, one might move aa01-aa02-ab03, or aa01-ab02-ab03,
paths which do not intersect except at the endpoints.
