{{[MetricResults._matches_sub_path|https://github.com/apache/beam/blob/5b46b02b49ca1c5c18682427a5a4a25596ca4287/sdks/python/apache_beam/metrics/metric.py#L152-L163]}} can be fooled into a false-negative if a path component before the one it is looking for is a superstring of the one it's looking for.
