Na it's in two separate areas I think. Henman Hill will always be there I feel. Murrays viewing area is called Murray Mound (another form of a mountain/plateau). I think Rusedski didn't get one because no good use of alliteration was involved, you could do Rusedski Rough but that's not as appealing as Henman Hill or Murray Mound haha.
Edit: Actually, I just wikipedia'd it and they are all in the same area. Also whenever Rusedski played, they did change Henman Hill to Rusedski Ridge.. didn't know that either so there you go!
