The last value that was generated outside of a test clause is the
result of the verb.

But it's not being displayed in the verb -- it's being generated as a
result.  The display happens later.

In other words:

shuffle=: 3 :'cube [] move"0 ] 3|?~y'

The [] pair will delay resolution of the value of cube until after the
results from executing move have been completed.

FYI,
