I'm with you . . . surely, if either dam or sire are shared then they are half siblings? If not, can someone explain how that works?

It's just the way it works and always has in horses. Siblings share a dam. If you want to be pedantic, you could argue the mare brings more to the equation anyway so siblings are more likely to share commonalities than horses by the same sire.
