I always heard that the number of nines was after the point, so that'd be zero nines. Two nines would be 99.99%

That's wrong. Five-9's for example, is 99.999% uptime, or a bit over 5 minutes downtime per year.

Maybe you're thinkinng of the actual proportion value. 99% can more simply be written as 0.99, which is two nines after the true decimal point.
