I've had a look at the changes and am more comfortable with the doc now. Feel free to republish.
Also, with regards to a question in the doc:
//What is the plan referred to here?
The plan for an overcloud is the heat templates stored in the undercloud's database that is used to build and configure the overcloud. Usually it corresponds to a heat stack on the undercloud. This is discussed earlier in the doc, if I remember correctly.
