Nope, the example you provide does not cause a collision, but it is clear you don't quite understand scope or conventions for using "getters" and "setters", which is what you are trying to do in your example.
Btw, taking 2 seconds to create a fiddle would help you understand things better and would let this forum help you in a way which uses real code.
