Default Would this Work or be Compliant?

I discussed this with another electrician. He modified one of the ungrounded conductors of a MWBC. The modification required AFCI protection. The main breaker panel is a GE panel. He installed a GE AFCI circuit breaker on the ungrounded conductor he modified and installed the grounded conductor on the AFCI circuit breaker from the MWBC. He did nothing with the other circuit breaker other than putting a handle tie on it and the newly installed AFCI circuit breaker.

Edit:

He said it worked. Is it actually compliant?

It would not work and it's not compliant.

Until the other half of the MWBC brings “stray” current into the AFCI breaker

Why wouldn’t it work? Why isn’t it compliant? Please explain.
