I agree completely. I was just suggesting a possible reason for the rule.
As far as your two All bet scenarios, even before I read the other replies, I was gonna say that they are the same. However, that wasn't how I read your description earlier. Was that what you intended?
Of course, because of it's high house edge, I'd be surprised to find a casino that's willing to have come-out rolls not count. That means they get their edge slower / less often...
I'm trying to reason out what I saw, or think I saw, at the IP. I did not play it enough to be able to recall for certain.
The casinos already have the Place and Come bet odds off on come out rolls. Most places have now turned the hardways on by default, but they make sure everyone still says whether they want their hardways ON or OFF. (I assume they changed to default on because it is a center of the table bet, which are almost all one roll bets and working on Come Out rolls.)
So the Small, Tall, and All bets are at the top of the center of the table, but I think that is primarily so the box can easily track the numbers that have rolled.
From a pure take perspective, the house would have all the bets, Small, Tall, All, Hardways, Come Odds, Place bets etc all working all the time. After all, they have the edge on every one of the bets. the only bet that works all the time is the LAY bet, but the player has the edge on the bet, and the house already took their 5% when the bet was made, so the house really could care less if the bet is working or not.
So, I think it boils down to how the casino feels the Small, Tall, All bet flows with the other bets. Do they align it with the Place bets, and have it OFF on come out rolls, or do they align it with the Center Table bets, and have it working all the time?
If they run it like the place bets, that means you can only bet it before the first roll of the shooter, which makes it play just like the Fire Bet, ie. bet on it before the shooter makes their first roll, or wait for the next shooter. This makes it fairly easy and clean to administer.
If they run it all the time, then they would need to remind every one, after each 7 rolls, that the Small, Tall, All bet is once again available to bet. That could mean a lot of bets up and down after every 7 rolls, including the come out 7s.
