Redundancy of "Redirection hint indication" in SDM vol3, 10.11.1

In SDM vol3, 10.11.1, SDM says :

"Redirection hint indication (RH) — When this bit is set, the message is directed to the processor with the lowest interrupt priority among processors that can receive the interrupt."

If I want to send a msi with lowest interrupt priority mode, I just need to set Delivery Mode in MSI data register to 001B, so what's the meaning of the existance of RH in msi address register?
