That tells you precisely how the the terms "faster" and "slower" are
used _in that article_, in order to avoid misunderstanding by readers
whose usage may be different.
It is exactly the same kind of remark as:
> I ALWAYS use speed ratio, say 1.143X, to avoid this ambiguity
except that it does not confidently claim "ALWAYS".
