Mostly it has found TDX module issues. But recently it added this case which turned out to be a general issue. The TDX specific MMU stress test is not ready yet, so Yan added the case to the general test and fixed it for both VM types. For TDX, since it's an pretty edge case and nothing catastrophic happens, I'd prefer to not rush a fix into the TDX PR.
