Yes, pageviews get incremented during reloads/refreshes, if those reloads/refreshes cause the s.t() script / Adobe Analytics Send Beacon action (if using Adobe Launch) to run again.
Yes, pageviews are measured in a similar way in both AA and GA, i.e. based on when the tracking call is run in the page.
AA has a metric called "Reloads". As the name suggests, this counts the number of pageviews that were actually reloads. So if you want to count the number of first pageviews, you can create a calculated metric of Pageviews - Reloads.
Hope the above helps!
