symlink to symlink confusion,
 

I came across this symlink to a symlink

$ cd /usr/java
$ sudo ln -s $PWD/jdk1.7.0_05 latest
$ sudo ln -s $PWD/latest default

I'm confused about the second symlink.
I know It points to the same directory as 'latest'
/opt/JDK/jdk1.7.0_05
It seems from the syntax that 'default' would point to
/opt/JDK/opt/JDK/jdk1.7.0_05

Why would you think that?

/usr/java/default will point to /usr/java/latest
/usr/java/latest will point to /usr/java/jdk1.7.0_05

Ok. I get It! I was thinking about It like a symlink was some kind of variable that holds a path but It's Just pointing to something.
I don't know why I had that Idea In my head.
Thanks.
