[Jprogramming] rank trouble

[Linda Alvord]

    pi=: 3 1 4 1 5 9 2 6 5
    e=: 2 7 1 8 2 8 1 8 3
   
   pi (]-.]-.[) e
2 1 2 1 3
   e ([ -. -.) pi
2 1 2 1 3

Since there is only one  2   in the nine digits of  pi  , isn't the only
correct one?
   
   e (]-.]-.[) pi
3 1 1 2

Without the "nub" gives an arguably more correct answer:

   pi (]-.]-.[) e
2 1 2 1 3
   e (]-.]-.[) pi
3 1 1 2

Why not

e ([ -. -.) pi
2 1 2 1 3 
?
