"Every entity belongs to an *entity group*, a set of one or more entities that can be manipulated in a single transaction. ... An entity without a parent is a *root* entity." ie. You can't NOT set an entity group for an entity. If you don't explicitly set one it will implicitly be it's own entity group. An entity group with only one entity will not therefore be in contention with other entities.
