With rings as thick as you have, then if you went through a whole growth ring, there would be a noticeable deep furrough creating a lowspot.
It doesn't look like that so I bet you are fine.
Very easy to cut through moon rings on thick ringed osage, especially if you've mainly worked only thinner ringed stuff. Done it plenty of times myself. You need to take a different mental approach, and consciously remember how thick it is, and when you see some chalky stuff, that its time to stop working that spot, rather than plow right through. Easier said than done, sometimes.
