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.

The article remove %faster ambiguity, but still is misleading.
Readers will not know it can only be used _in that article_.

I thought it were just a *reminder* of terms, not a re-definition.
A better reminder is to say X% faster meant X% faster in speed.

Another case of "faster" re-definition:

Spooky! Quantum Action Is 10,000 Times Faster Than Light

How fast do quantum interactions happen? 
Faster than light, 10,000 times faster

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".

But I DO !

Speed ratio is much more precise than "% faster"
(Besides, I were un-sure what "% faster" meant ...)
