Why is this function placed at the end of file?

Good point. I moved it under ClearAndRestart...

+  DCHECK(thread_checker_.CalledOnValidThread());
+  // Sync has a restriction that the engine must be in configuration mode
+  // in order to run clear server data.
+  engine_->StartConfiguration();
+  engine_->ClearServerData(callback);
+}

 }  // namespace browser_sync
