I don't quite understand that. Does it mean to check that none of the n addresses in the RH4 matches any of the current node's interface addresses? But at least one of them must match, since packet was delivered to the current node.

Whereever possible, including the administrative network edge, RPF check needs to be done.
If RH4 is being used to diagnose routing configuration errors, an RPF check is quite likely to fail, so this recommendation seems to defeat one of the purposes of RH4.
