More than "reported", they are known to count towards MM status. MQMs are MQMs, DL doesn't distinguish between the different sources for MM purposes.
I actually crossed over 1MM by claiming Reserve MQMs, which was anticlimactic, but the trip I would have hit it on first got rescheduled
Anyway it's simple enough to verify by comparing your MM total before and after an AMEX boost.
