You are correct, the hourly diff imports can not handle the multipolygon relation properly. These will fix themselves after the weekly import each Wednesday. Any edit to the nodes or ways in the relation will probably break it again. Overall the benefits of the hourly import far outweigh the slight problems with the multipolygon handling. Feel free to raise a bug if you want. I'm sure someone will get around to fixing it eventually but I have other things to look at right now.
