It's nice to see the "correct" order of the registers being used. (The reason for this ordering is in the realm of trivia questions.)

Do you mean "correct" as in that's the absolute right order (as in math) or as in that's the original intel syntax?

My first programming language was mc68k assembler where the "correct" order of registers is the opposite.

It's the order they occur in the encoding: A, C, D, B.

68k has numerical, not named registers, and they're in the same order as the encoding.
