Can a node from a logical hierarchy be used as a reference to define the Work Order Asset Route?

When creating a logical hierarchy for Asset Route, a 'Work Order Asset Route' has to be defined and it is a logical hierarchy based on a maintainable asset that represents an activity or a physical location such as a plant, building, floor, or a production line… (Referenced from Execute Maintenance for Asset Routes), and then update the hierarchy with applicable assets (child level 1)..

Question is, the 'Work Order Asset Route' is just a placeholder for a work order to be referenced from, but the assets are from the logical hierarchy? and there's no hierarchal link between the Work Order Asset route and the hierarchy?
