They tested their new algo (to boost the home pages) on regular samples and your case (too sites on the same IP) is not typical. They cannot check all. So it is better to be as regular as possible. I unfortunately am doing the thing similar to you, adding the new topic for the existing site. The only hope is that my site name is neutral so it will not frighten the customers. I never tried it myself but why not to change the IP for your keywordwordphrase? I believe that it should do no harm because, if I understand correctly, all good hosts have spare server with the different IPs for the same site. However again, it’s just theoretical. I have no my own experience. Vadim.
Probably it is a pure Google bug.
