Yes, these weird things happen from time to time and other weird things too, like nodes with no branches, nodes with one branch, self topping branches and nodes with no branches but with 3 leaves being some of them.
Sadly, although you have more "bud sites", the flowers growing from the 3 noded branches are almost always smaller than the flowers growing from the "normal" 2 noded branches. It is more like 3 medium flowers and 2 normal flowers, and not 3 normal flowers and 2 normal flowers, when comparing flowers on the same plant but growing on different branches, one 3 noded and one 2 noded. And yes, I am talking from experience, having seen this anomaly a few times in my grows over the years.
Hope this helps,.........
