Not sure if it is what the GPP is referring to, but I prefer to keep a larger gap between my browser and password manager to reduce the potential spread of difficulties if the browser falls foul of a security vulnerability. The risk of this happening is of course small, it would require significant bugs in a couple of different places, but the potential damage is high. Firefox's password manager, or those built into any other web UAs, I'd be wary of for the same reason rather than it being specifically an anti-chrome thing.

An air gap would be preferable still, as that would protect from similar issues at the OS level, but that is another step or few into less practical (well, significantly more inconvenient) territory. I at least have my master password on a USB device (and backed up by other physical means in case that dies) which is only plugged in when needed, that is effectively an air gap when I don't leave the password manager unlocked between uses.
