Technically you're correct but let's not act like the N55 variant in the M2 was a revolutionary transformation
From what I can remember the only upgrades the M2 got over the M235i (engine-wise) was: slightly modified pistons, magnesium oil pan, an improved oiling system and a couple other things like different manifold or crank bearings.
There are differences, sure, and that's why I'm telling you that you're technically correct (and I added a note on the OP) but since the majority of the engine components stay the same , the video is still good information.
