It's not necessarily bad; many modes define their own movement commands.
You still haven't told exactly what you are doing, so I cannot tell.

Maybe this was only example code, but I'll point out anyway that it's in
bad style. Use descriptive names and write a documentation string, so
that one can at least guess what the function does.

What makes you think that? Did you try it?
