Hello Robert
Thanks for sharing that. In this instance it looks like the securityk9 feature has been installed, and three licenses have been applied, each for a duration of just over 208 weeks. The result is that these licenses will be applied consecutively thus you will have a license duration of (208 weeks 2 days) X 3 which is almost 12 years 
.
Notice that in the show license output, it gives you the total period left of 604 weeks, which is the cumulative remainder of all three licenses.
Indeed, when the currently active license expires, it automatically rolls over to the next one. No need to do anything to get that to happen.
I hope this has been helpful!
