I guess I can see what you are saying. The way I read it, it is part of step 2. I think it is just treated kind of like common sense basically saying "fly the airplane."
The common sens will not guess that the pilot have only maximum 5 seconds to go from the second indented (could be misinterpreted as only if AP engaged) point 2 to the first indented (could be misinterpreted due to MCAS discontinue action) point 5, and that all the next points can't be done at high speed. Under stress and without appropriate specific training, this procedure as redacted could easily be error prone.
Don't focus on MCAS in this case. If the training isn't adequate for runaway stabilizer then it is an issue for ALL causes of runaway stabilizer. If they (specifically the ET crew) didn't run the NNC properly for an MCAS induced runaway stabilizer, they wouldn't have run it properly for runaway stabilizer caused by something else.
