Network Wide Client Isolation with a VLAN pool

On a large network with a single WLAN that requires a VLAN pool (large number of client devices), does Network wide client isolation access still work. 

The question comes from a large school division with up to 10K devices. They want a single WLAN with network wide isolation. A VLAN pool would be meet the client requirements but I don't know if isolation works or breaks with a pool.

Anyone tried this?

This scenario is tested and it should work. But to be noted inter vlan reachability will be always there whether you enable client isolation or not. Client isolation will work only in same vlan means if two stations are part of same vlan.
