Here’s an example of a model having more prints than downloads: https://forum.bambulab.com/t/show-successful-prints-number/55803
It’s not common but some models here and there have more prints than downloads, and this is before the latest changes to how downloads are counted. This must mean that a download that results in a successful print is changed from a download to a print in the counter
So basically nothing miscounted, they just move it from download counter to print counter and as OP stated they know a print counts for two downloads and so having both counters record the same download/print would represent triple points
