Is 999dice proof of fair play not really proof?

Question

Cryptography

There is a site for playing dice
Bitcoins are accepted as bets.
The essence of the proof of fair play is as follows: 1. You
are sent a ServerSeedHash
2. You place a bet - send it to the ClientSeed server 3. The server
Calculates the Hash from (ClientSeed+ServerSeed+bet number). Then it runs this hash through its cycle and calculates the number which is the result of the game.
4. The server sends you in response the received figure, the bet number, and other attributes: such as profit, balance, and so on.
There are nuances - in the "Fair rates" tab in the example of the description of the function that calculates the final result of the bet on the server - the bet number is not specified. Instead of (ClientSeed+ServerSeed+bid number) it says (ClientSeed+ServerSeed).
However, below - in the example of verification, which can be carried out on the client side if desired, the hash is calculated precisely from ( ClientSeed +ServerSeed+rate number
) result?

there seem to be sorts. However, do you think under NG someone will reverse and audit the code?
