Yes. These are really about "live with the stone or somewhere else

Would changing it to owl_defend R15 be sufficient to make it correct?
Otherwise it doesn't worry me too much if it's allowed to get away
with a good but technically incorrect move.

There are probably several alternative moves missing among the rest of
the test cases as well. You're welcome to review all of them.
