                           FastIterator rightTupleIterator)

Description copied from interface: RightTupleMemory

The FactHandle is always the context fact and is necessary when the object being modified is in the both left and right node memories. This is because the memory on the opposite side would not have yet memory.removeAdd the fact, so it could potentially be in the wrong bucket. So the bucket matches check always checks to ignore the first facthandle if it's the same as the context fact.
