emergency ATS connected load side of optional ATS

I am reviewing plans that specify an emergency system and a optional system, the generator has 2 breakers one for each system, but the optional system ATS is specified to be installed to re-feed the entire existing 800 amp switchboard.

The emergency ATS is connected to a breaker in that same 800 amp switchboard that feeds the normal side of the emergency ATS. Will this work with the optional ATS re-feeding the normal side of the emergency ATS or any code issues with this setup, thanks in advance for any help
