Monitoring alert policy on public versus private bandwidth

A Droplet with Shared Private Networking enabled shows four independent metrics for Bandwidth: Public Inbound, Public Outbound, Private Inbound, and Private Outbound.

When creating an Alert Policy, the only relevant metrics available to choose are "Bandwidth -- Inbound" and "Bandwidth -- Outbound". How are public versus private bandwidth metrics treated with respect to alerts?

For example, if I have a Droplet which, during normal operation, averages 10Mbps bandwidth on Private Inbound but near-zero bandwidth on Public Inbound and I define an alert policy for when Bandwidth Inbound is below 5Mbps, will the alert trigger immediately because Public Inbound is below 5Mbps or will it only fire if Private Inbound drops?

Similarly for an alert on bandwidth exceeding a high threshold, does the alert trigger when either Public or Private increase, or when the sum or average of the two exceed the threshold?
