Is this the uncertainty principle or diffraction?

Consider the following video...

Am I really seeing a demonstration of the HUP or am I just seeing diffraction?

In this instance, is it just different models with different terminology describing the same thing? If so, what scenario would require the HUP? What can you not model with wave equations that can be modeled with the HUP?

The diffraction that you see is a clear example of the HUP at work! See this:
