Nope, just one. The MSCHAP challenge & response arrive at you, you
validate them and in turn generate the response2.

You might be thinking of the first pass in EAP-MSCHAP, where the client 
sends EAP-identity and the server sends EAP-MSCHAP challenge, but that's 
stateless - just a random number. Likewise, the 3rd pass MSCHAP 
success/fail packet is stateless.
