32 Max HA events, what then?

In the maximums guide for 5.1 it states that max concurrent host HA failover events are 32.

My question is what happens if you have 64 VMs running on a host and it fails? Do the first 32 boot up, and then after they have finished the next 32 boot up?

Thank you kindly,

Steven
