It's hard to isolate factors, but two travel-related EMDs I watch have, if anything, moved up in this and other recent updates... for the branded keywords and for related terms and stems.
I had optimized these a while ago, and I can say the linking on at least one of the sites was very solid and a lot of work was put into some of the content that related to the brands, not nearly as much as I'd recommended, but enough to merit some very good backlinks and to hold core rankings.
I was also very aggressive with the client about getting junk inbounds removed at the time I dealt with the sites. It amazes me how many times you have to argue with some clients over stuff like this.
