I like this approach. "funny meme" aside, I think it is a good way of showing how much a certain language can affect how other people think and feel about a subject. Just read it THAT way and "being neurotypical" suddenly sounds like a disorder that isn't fully compatible with the public, doesn't it?
We live in a world that isn't exactly kind to people on the spectrum. It is loud, flashy, hectic, overwhelming, unrewarding but you're still expected to work like a cog in a machine, despite having fewer and fewer places where you'd actually "fit in" without grinding gears, and whenever there is some sort of public talk about that topic, it always, always sounds like the affected person is the problem and personally responsible for fixing themselves, when a no small part of "not fitting in" is due to society itself. Maybe a change in language is due to remove that stigma.
I would be willing to bet actual money that they did not mean those exact specific lines and colours, and instead provided them as direction for the type of organisation and presentation of the data they were expecting. They wanted it presented in a manner that made the comparison easier to digest at a glance, and not just a trivially assembled side by side list of plain numbers.
Think about the reason behind the request, and how it changes the situation for the person making it. Could they have gotten a dump of unformatted data themselves? If so then that's almost certainly not what they're asking for.
You literally asked how a short instruction expands to include these seemingly expected additional formatting requirements. The answer is that it doesn't expand to exactly these arbitrary requirements, but that a certain style or level of aesthetics was implied by being a work environment. Unless your boss is hard to work with and actually demands a specific date format and color coding. Most likely though, they want any form of color coding to distinguish different parts of the spreadsheet at a glance and a reasonable date format that is used in everyday life.
