Does Z2M work with multi-protocol on skyconnect/yellow

I’m thinking about getting either a skyconnect or a yellow in the new year, but i can’t figure this out. the CS post outlining multi-protocol support seems to imply that both zigbee and thread are handled by ZHA, is that just a convenience because ZHA is already built into home assistant, or does multi-protocol only work if both are being handled by a single program?
I don’t have either device so I can’t just try it out
