NFPA 96, in regards to Kitchen systems 10.2.6 refers you to NFPA 17A wet chemical systems.

17A states that exhaust fans and dampers need not shut down, as the systems have been tested for zero and high velocity flow conditions.

I can not find MAU shut down in 17A. the closest would be "all fuel sources.." must shut down.

In 96- 8.3.2 it shall shut down on activation of system.

I would see (NFPA 96) chap 8 and 10 as 2 independent directives.
chap-8 says to shut down MUA.
chap 10- refers us to NFPA 17A and MFGRS instructions.
