Using queue(s) causes dashboard stats to inflate

So I switched from using a Ring Group to a Queue, and it’s great.

Do I understand correctly, that as the Queue takes the incoming call, it creates a call to the extension that answers, then bridges them - which causes, in certain situations, the number of calls to rise +1 per call (e.g. when 2 calls ring at the same time, you’d get a statistic of 4 briefly, then going down to 2 again) ? Or is that an effect of some setting I’m using (I have ‘queue no answer’, ‘autofill’, and ‘mark calls answered elsewhere’ enabled, ‘skip busy agents’=no, join empty and leave empty = yes) ?
