I looked at the bettysplendens website and it explains the types of Plakats. From what I understand the 2 rayed bettas are (asymmetrical) traditional plakats and most of the thai bettas are (asymmetrical) show plakats which have four rays.
This explains it better,
I expect to pass through this world but once; any good thing therefore that I can do, or any kindness that I can show to any fellow creature, let me do it now; let me not defer or neglect it, for I shall not pass this way again.
