It's certainly no less boring! But still an annum X chinense hybrid.
The effects of crossing a F1 with another chili is more or less the same as a "normal" F2. You get a mixed set of genes from the F1 parent and a fixed set of genes from the stable parent. I.e. all seeds will carry a different set of genes. Theoretically the offspring plants should, on average, tend to be more like the stable parent, but again that really depends on which parent has genes that dominates more than the other. If you only grew 1 plant, and are happy with the result, forget the theory
and grow out the as many plants of the next generation as you can. Select the best and repeat. When you reached a generation where all the plants seem the same, you have a new variety
