This is a non-problem, or at least a non-unique problem. It is the exact same thing as using variables as function parameters. Sometimes what the variable means in one place is different from another place, so... you use different names. This surprises no one except maybe first-time programmers. Sometimes a variable means nothing and we can give it a single-character name, but then we shouldn't have a bunch of them to get confused by.
