Can two licenses support six instances?

I have read the SQL Server 2022 Licence Guide with great care. As far as I can tell, the following is a perfectly valid licence configuration if you have **two licences and Software Assurance**. Assume that I am talking about the same AG throughout. |Server Name | Location | Setup | Covered by Licence | |:---- |------:| -----:| -----:| |Prod Primary | Main data centre | Production Primary, hosting exactly one AG | Licence A - Primary | |Prod HA | Main data centre | Automatic failover AG replica, synchronously replicated | Licence A - Free HA server | |Prod Manual Failover | Main data centre | Manual failover AG replica, asynchronously replicated | Licence A - Free DR server| | DR Readable | DR site | Readable AG secondary, failover/replication don't matter | Licence B | |DR HA | DR site | Automatic failover AG replica, synchronously replicated | Licence B - Free HA server | |DR Manual Failover | DR site | Manual failover AG replica, asynchronously replicated | Licence B - Free DR server| I find it surprising that this seems allowed. **Am I correct that it is allowed?** Obviously, Microsoft has the final say on anything like this. However, what I'm describing here *must* be so common that the professionals here have either seen it before or already know why it does not work.
