Is this the HUP 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:

Thread 'Quantum behaviour of an electron around a positively charged sphere'

If we release an electron around a positively charged sphere, the initial state of electron is a linear combination of Hydrogen-like states. According to quantum mechanics, evolution of time would not change this initial state because the potential is time independent. However, classically we expect the electron to collide with the sphere. So, it seems that the quantum and classics predict different behaviours!
