Active Passive HA licensing with a Software SFV4C6 firewall

We have a SFV4C6 firewall loaded on our own Intel Hardware, it has the Base perpetual license along with a subscription for Enhanced Support, Network Protection and Web server protection.  I want to setup a passive HA pair and I have the matching hardware already.  What additional license do I need to purchase to get the passive firewall setup?

It seems like I would just need the Base license (Part number XV4C6Z00ZZPCAA) to get a second Base perpetual license.  since from what I understand the Enhanced Support, Network Protection and Web server protection subscription will work for either device in a HA Active-Passive setup. But my Account Rep is saying I need to purchase a second "subscription" license for it?
