It does something slightly different. My version always jumps to the
first jump in the current file (and won't leave the file), while
Marcin's version always jumps at least one file backwards or forwards
(and thus won't solve the issue, the OP noticed).

Now that I think about it, I guess my version also does not fully
solve the OPs original question, as he wants <C-O> to stop at
file boundaries. Oh well, I guess, I misunderstood something.

I think, this is just a matter of being used to.
