It's better that the receiver controls them than big vern. After the auction is over there will be no more fear of a massive dump. If big vern controlled them investors would never buy in because of the fear of him dumping.
Unfortunately I think the receiver will sell to the highest bid even if it's a ridiculously low price bid. I have not read anything about a reserve price being set yet.
'The fear of a massive dump' is the everlasting fear in the crypto world. Fear and Greed drive crowds, you know.
The reserve price is the lowest price the seller is prepared to accept for the property, but there is also the starting price. If they sold coins without setting an appropriate reserve price/starting price, that would be unfair. After all they are not interested in selling low, so probably they will set fair prices.
