Will I get mistaken for another person while going through the n-400 process. If so what can I do to prevent or handle this.

A person lives near me with the exact same name. He is apparently also a permanent resident. Will I get mistaken for him because we share same names and live near ea other? When I applied for green card renewal they told me I already had a green card and I had to explain to them that it was a different person. Getting the n-400 is a very long process, it is horrifying thinking that they will mistake me again. They can't be that incompetent can they?
