Pix: LAN Failover - Cross-over Cable Won't Fly

At the informational link below - we are informed that when using LAN interfaces for failover link you must go through a switch and not use a cross-over cable between the two pixes in the pair. It does not however explain why this is the case. Does anyone know why a switch must be involved in the picture to make this work?

Re: Pix: LAN Failover - Cross-over Cable Won't Fly

Cable based failover is used in statefull failover,The importance of switch is that the primary and secodary pixes should be active in the network.
