In a sense your mx has "stacked" the two tables alreasy. An you can get them 
back without fills.

 

 [mx =. (i. 2 3) ;<i. 4 3 

┌─────┬───────┐
│0 1 2│0  1  2│
│3 4 5│3  4  5│
│     │6  7  8│
│     │9 10 11│
└─────┴───────┘

   $mx

2

   >0{mx

0 1 2
3 4 5

   >1{mx

0  1  2
3  4  5
6  7  8
9 10 11

 

 

Maybe all you want is to get each one back again.

You're right again... but I was thinking about cases where y is a list of boxes.
