My assumption was that since they do receive a lot of email, they have statistics on this, but of course you may not agree with that assumption and assume that they're just doing this for whatever other arbitrary reason.

No doubt they're good at what they do, but if mta operators felt that Google's FP detection rate was acceptable for v6 originated mail, we wouldn't be having this discussion - particularly as the other major mail operators don't appear to have this issue.
