I'm sure your guide just misspoke, and it is probably an understandable mistake. I'm sure if DVC ROFRs a contract with points in holding status, they just throw the points away. But, as Tom said, in a resale you will get whatever points are present in the contract at the time of closing. Everything will be specified in the closing documents.
Whether holding points are of any real value to you, however, is another matter. Be sure you understand what they are and how they must be used because they are not "normal" points.
Holding points can only be used for a DVC property reservation made less than 60 days from check-in, or a Disney, World Passport, Concierge, or Adventure Collection reservation made less than 60 days from check-in, and more than 60 days prior to the end of your use year.
Those are severe restrictions, and you are going to have very limited availability less than two months out. The points are not unusable, but you are going to have to be flexible enough and take whatever you can get.
