You end up with the same amount of money on the Point and in the Come with the difference being the $5 that was won. Your new Come bet (same amount as the first) would then move into the Point (same as the first).
Your Come bet ($5) would come off the Point with its winnings (another $5). Let’s say you have $5 on both a Point and another in the COME then that Point rolls. When you have a Come bet in a Point and you have a Come bet of the same amount in the COME then that Point is rolled, you have what is called “Off and On”.
