yes I think it would consider all comparisons different; from what I
understand it gives the fuzzer a better understanding of which part of
the input needs to be altered to follow a different code path.
Anyhow the libFuzzer documentation at
https://llvm.org/docs/LibFuzzer.html says: "This may slow down the
fuzzing but is very likely to improve the results."
