Note that the same index into y appears multiple times in m

Here's an illustration of what that means if you're using Amend:
  7 8 9 (1 1 1}) i. 4
0 9 2 3

Is the problem you're having that you don't
want only one of the changes to happen but 
instead want these operations to take place 
sequentially?

Thanks,
