Because the original comment was about the appropriateness of writing Python code according to the reference implementation as opposed to writing Python code strictly according to the reference document. Some people are arguing that the reference documentation is in some sense authoritative and the only resource that should be used to define Python's semantics. In particular the issue at hand is whether the GIL is a part of the semantics of a Python program. As my position is that the CPython implementation is the reference implementation for Python and as the GIL is an integral part of that implementation, then the GIL does form a part of Python's semantics regardless of whether the reference documentation mentions it or not. The Python reference documentation is not a specification and it's not intended to be one.
