I'm guessing there may still be a tiny window while the metric sdk is still collecting metrics but before it has sent them to the metric exporter(?)

At time of writing, that PR was causing clearData to first flush the metrics SDK. But realized it's not necessary or helpful in most tests so changed it back, so indeed this comment is now invalid
