I think it was 50% more buy-ins than you had for the previous level, not BB (big blinds).
But yes, if you start with $100 and play $5NL (standard 20 buy-ins), then to go the next level $10NL you should have 30 buy-ins for that new level, or $300.
That's how I remember it. Pretty conservative, especially as it gets quite exponential if you continue doing so up the ranks but I think his reasoning is that variance is going to bite you and you need some buffer in the early stages while you adjust to the new level.
