Yes, this is expected behavior. The MatID settings in the Voronoi fracture modify the meshes directly and immediately....whereas the Material ID operator assigns a particle override that is applied at the time the final tyFlow mesh is built. Assigning a Material ID operator and setting a static material ID value of '0' on a particle allows you to remove the override, in the case of voronoi chunks that received an override earlier in the flow.
