Not really, that's more related to the fixed precision of IEEE 754 floating-point numbers. In any fixed-precision representation there's always a certain representation which happens to be the best approximation of any constant like pi. That's the one you would pick.
However, you could perhaps infer from the article that IEEE 754 double-precision numbers are sufficient for most physical calculations.
Other way around, they use that value because that's the most precision you get with IEEE-754 64-bit floating-point numbers, which is the representation also used by JS for floating-point.
