We were discussing this on a similar thread. I don't think its a guarantee, but it lowers the probability of a buyback if its well into the future. If its only delayed 1-2 months I dont think it has any impact on Disney's decision. It can be a way to get a better deal, many aren't willing to wait to own or they want to use their points right away. Others have mentioned that there is a higher risk of a seller backing out, but others advocate for this method if you know you arent visiting for over a year and want to lock in a lower price.
Bought and sold three this way, All passed within a short time. One even in like 6 days,
All offers were within the line of prices of what was passing ROFR, So, I don’t think the delayed closing played a role in the decision of passing on it.
