That's a very old version of the Process. Here a persistent link to the 
currently-operative one:
   http://www.w3.org/Consortium/Process/
and, perhaps more relevantly, the one that will be effective starting 15 
September 2020:
   https://www.w3.org/2020/Process-20200915/#rec-track
and its corresponding Patent Policy:

The quality and level of detail of implementation reports varies among WGs, is 
my impression. Ultimately the Director decides whether the implementation 
requirement has been satisfied.

Fwiw, here's the CSS Writing Modes Level 3 implementation report:
