lol, no. Galaxy brain starts somewhere (generally sane and reasonable) and then moves progressively in a certain direction (generally more complicated). In this case the starting point is an instruction sequence that is reminiscent of RISC architectures and then it gets progressively more CISC as you go down the page. The whole point of galaxy brain is that it follows this sequence, and because there’s no special third panel the sequence is extensible to arbitrary lengths.
I've seen galaxy brain comics where the last row is the punchline. The comic might start out moving in a certain direction in a logical way, which may or may not be humorous by itself, but then the last row has a twist, an unexpected interpretation of the direction.
The x86 comic may or may not count, depending on whether you expect the reader to know that using those sorts of legacy instructions is not actually an improvement…
Sure, my point is that the twist doesn't need to be at a particular point, nor does there even need to be a twist. It's just a progression of related images–I think the progression in the ones you're showing is similar to the "evolution of a programmer" joke where a junior engineer starts off with something simple, progressively makes it cleverer and more complicated as they learn more, and eventually return back to the simple solution.
