Not necessarily domino as it didn't really create another great migration. Many Turks from other regions migrated to anatolia to fight and gain lands, that's why the boom happened after mankizert as Alp Arlsan allowed the commanders hold the land they conquer, it become stagnant after over centralization.
Also in the west both political and military entities were disrupted, so there was always a chance to fight against them or be mercenary for them. More or less 'Turcia' wasnt solely entity of Oghuz Turks, it get Turkish immigrants from many other places.
