yorick's q is a bit wankily worded

Why does his spell last rights say when there are 3 or more graves and last rights has been used, yorick can cast awakening to raise mist walkers. This has me stunned because none of his attacks are labeled as awakening. Why does it not state yorick can recast last rights??? Is it not that hard to keep things simple? I understand you guys wanting to get words right with revivals and bringing to life, but don't go giving a move set new names. It is confusing as hell. I can learn to use q and what it means now, but the wording is ridiculous imo and hard to understand. Was wondering if q w e r would cause the effect besides recasting q. this is causing an unnecessary learning curve.
