To add to Vitaliy, VEB keeps 14 days of successful backups. This means not 14 days in the classical way of thinking but effectively 14 days. As an example. Imagine that you have 7 days as a setting, and your computer succeeded in backing up Mo to Fri. At that point you have 5 days. Then you skip the weekend (computer off or whatever reason). On Mo and Tue you backup again. At that point you have 7 days although there are 9 days passed. Only on Wed pruning will start.
On top of that, if you (for whatever reason and based on your settings) take 2 backups a day, you will see 14 recovery points because it is about the days, not the amount of recovery points.
