The first COMP→ DROP leaves the System RPL program :: xHALT ; on the stack. The second COMP→ DROP explodes the program and leaves the xHALT by itself.

I find it interesting that the :: xHALT ; System RPL program takes up 7.5 bytes while the bare xHalt takes 12.5 bytes. Of course, you need the bare command for the assigned key to have the desired behavior, but still interesting.
