I'm not actually seeing this being endianness-independent.

Is the input just regular 32-bit data in native word order? Because
then it's not endianness-independent, it's purely that there *is* no
endianness to the data at all and it is purely native data.

So the code may be correct, but the explanation is confusing. There is
absolutely nothing here that is about endianness.
