All asserting Facts must propagated into the right ObjectSink side of a BetaNode, if this is the first Pattern then there are no BetaNodes to propagate to. LeftInputAdapter is used to adapt an ObjectSink propagation into a TupleSource which propagates a ReteTuple suitable fot the right ReteTuple side of a BetaNode.
