Consider a VertexGroup composed of 2 vertices, each with 2 tasks. If this is a union, then the expectation is that the VertexGroup has 4 tasks. A ONE_TO_ONE edge, to a downstream vertex, must then require that vertex to also have 4 tasks. This is not the case, as evidenced by the [following test|https://github.com/apache/tez/blob/261bbdd5929d562758deb31085b565db8e92d6a2/tez-api/src/test/java/org/apache/tez/dag/api/TestDAGVerify.java#L779-L831]. Rather, what happens is that implementation (of unrolling the VertexGroup and directly creating edges between the components of the VertexGroup and the downstream vertices) is presented as the behavior. was: A VertexGroup is described to act as a union of multiple vertices.
