No, it doesn't. As I recall (it's been a long time since I've messed with filesystem stuff), each namespace can have its own root dentry, and dentries are mostly used used for looking up inodes by their path within a particular namespace.
There is no real "absolute" path to a file because the kernel doesn't need it. Most interesting things happen at the filesystem/inode level.
(One of the reasons that people object to AppArmor is that it'd require pushing a lot of things up into dentry-land, when the whole system was designed around inodes.)
