Unreachable code

[lambdafu]

I'm not a Go expert, but aren't the three else clauses all identical?

func (a UUID) SameAs(b UUID) bool {
	if a.Value() != b.Value() {
		return false
	} else if a.Origin() == b.Origin() {
		return true
	} else if (a.Origin()^b.Origin())&INT60_FULL != 0 {
		return false
	} else {
		return a.Origin()&INT60_FULL == b.Origin()&INT60_FULL
	}
}
