Because it might not be "this".

What if you were using a TreeScanner to create a custom pretty printer?

Other parameter names are represented by Name, not a tree node, so they
can't be visited.  The nameExpression is only set for a receiver parameter
and is null the rest of the time, much like the "default" value on a method
decl is only set for a "method" in an anno decl.
