I have seen the opposite a couple of times too - a flower truss in the usual place which has leaves (but not a full growing tip) beyond the flowers. It's just natures way.
If you aren't sure about a side shoot, let it grow for a bit until it becomes clear whether it is going to continue producing new shoots and diverting energy from the main plant, or just stop as a branch or flower truss. It is never the end of the world if you end up with a double stem, it's just more efficient if you can get all the side shoots.
I often leave the topmost side shoots for a few days until I am sure the main growing tip is still going strong (had one stop prematurely once).
