That's just the syntax used to create a context for local variables.

All of these variants aren't valid syntax and won't compile:

Code:

« →
»

Code:

« → a
»

Code:

« → «
  »
»

You actually need all of this:

Code:

« → a «
  »
»

This doesn't create a code object on the stack as « CROSS » did.
It just indicates the scope of the local variables using the same guillemets « and ».
