You can find the same thing, right here, a few messages back.

The problem is, "twelve point" isn't the proper name for any type of
drive - it's merely descriptive. Think of the confusion if hex (allen),
Torx, and Polydrive were all called "six point." Best to just call
things by their proper names.

Having said that, there are "12 point" sockets, everyone agrees as to
what they are, and they're extremely common, so it makes sense that a
fastener which requires using those would also be called a "12 point,"
for that reason alone. If you have to deal with a ZXN or spline drive,
which also have 12 points, you need a much less common tool, so it makes
sense to be more specific when describing them.
