The convention used in this video treats qubit wires ordered from top-to-bottom as equivalent to left-to-right ordering in the tensor product, e.g. H tensor product I means H acts on qubit 1 (top) and I acts on qubit 2 (bottom). In other sources, you may also see the bottom-to-top ordering convention, which is the same as turning the quantum circuits in this video upside down.

I had a hard time to understand what a Bell measurement is, because I was confused by shorted explanations. This video makes it completly clear and also links the generation of Bell states and its measurement by linking the adjoint U operator with going backwards in quantum circuit. Thanks a lot.
