Path of War

If I get my first level of initiator class at character level that allows to pick maneuvers of level 3 or higher (these with Prerequisites: X maneuvers of said discipline known), do high-level maneuvers qualify for each other? For example, fighter8/warder1 have IL of 5, and five maneuvers to learn. Can he learn two level 3 maneuvers of one discipline (each of these maneuvers requiring him to know one maneuver of that discipline)?

Off the record: would doing so make me into book throwing target at your table?
