@vadler With this condition met, something was not configured properly and the final results should not be used until the problem is fixed. So in that sense, one could argue that it doesn't matter much to what value `matchedLocks` was set since the results probably don't make much sense anyways. However, I do agree that it is probably better not to set `matchedLocks` to `true` if this condition is met. The same is true for https://github.com/cms-sw/cmssw/pull/3994/files#r13046815 I will commit a fix soon. Thanks for spotting this.
