Anyway,  here's your code run in my session:

   down =. |. ] up =. i. # ] b =. ? 2 #~ L =. 10
   up =: b } up,:down
   up
0 1 7 6 4 5 3 2 8 0

I haven't attempted to check whether the result for up is correct!

This occurs with L = 10, but not necessarily with other values of L, and
not with '?.' instead of '?'
