Yes, just the metric name matters, not its labels.
After POSTing the 2nd push, you would end up with all the
external_ats_metric1 lines from the 2nd push (but none from the 1st),
the external_ats_metric2 lines from the 1st push, and the
external_ats_metric3 lines from the 2nd push.
If you use PUT, you would end up with only the lines from the 2nd
push.
All of this assumes you are pushing using the same grouping labels.
