Just illustrates the changing structure (increased nesting depth) on each recursive call
The initial call to t2 changes the structure of the <rest> argument/parameter - it puts in a list where there was no list. Each recursive call from inside t2 again changes the structure, adding an enclosing '() for the <rest> parameter For the usual (no <rest>) function call It's not an issue for the standard car/cdr idiom of walking down recursive structures.
