I'm fairly certain that it's quite different, when compared to decades if not centuries of past methods, all thanks to someone with a particular set of software development skills taking a new look at the already existing approaches and deciding to do something different.
It looks also like something that won't be used by anyone who is familiar with the existing approaches, generally happy with them and is just looking for tools that would help them with what they are already doing. The nice part is that nobody's trying to push it as a replacement for existing notation programs or DAWs.
