Yes AFAIK the new formula is correct.

fancySum(a, b) = a + b * (1 - a) == a + b - a * b

But I've noticed that even exponents as big as 9G (say, https://www.mersenne.ca/exponent/9040030253) have been corrected.

The data is all corrected, but if you've looked at an exponent page recently you're probably seeing a cached version -- use Shift+F5 to force a browser refresh and you should see the new numbers.
