I'm not incredibly familiar with the court cases, nor that of Coldplay/Satriani, but I have a hard time believing that their decisions are algorithmically binding. Like, yes, they might be similar along those particular axes but that doesn't mean those similarities are the sole reason for the court decisions. There's also matters such as - was songwriter #2 exposed to song from songwriter #1? Does the similarity in arrangement imply intent to copy? Etc.
