I read that too when I bought mine (LU-something), they came plain, not Lucas, and I'm still a little po'ed. This was a few years ago so I seriously doubt that they got new stock.
You could always call and ask. But let me know if they now have Lucase branded because I also need a couple.
edit: Just revisited the page and the front signal lens (amber L691s) are the ones that are still Lucas.
