I can't give you one because it's not mine to share. But I can tell you 
a couple of ways I have seen it come about.

One is when a piece if code is re-used in another function which happens 
to have a parameter name which is the same. Another is when translating 
some code and this is the simplest way to do it, with the least effort 
involved.

If I am writing a piece of green fields code, than like you I avoid 
this. But the vast majority of what I do for people is not green fields 
code.

In any case, it's not our responsibility to enforce a coding standard. 
That's a management issue, in the end, not a technological issue.
