When that happens to me I immediately say "Whoops, didn't get it on plane at the top with flat left wrist" and/or I didn't throw it down on plane.
I tell myself "extensor action, right forearm pickup, straighten right elbow throwing it on plane, right into the ground."
Oh, yeah, trust it. Fat/thin shots are a timing issue, in my experience. The left side didn't respond correctly on the throw.
