Actually no, they will be counted only once towards the period in which we
are counting them (daily or monthly) as long as the IP of the device is the
same. Not multiple times. In mobile IPs are shared due to NAT-ing and thus,
this method undercounts.
This is explained in detail here:

a device might use multiple browsers (especially the
embedded browsers on
mobile devices)
This is correct, multiple browsers on one device will be counted multiple
times. This is less of a common browsing pattern than using the same method
of access every time.

Sure, and browses which rejects or periodically delete cookies will be
counted multiple times, and a device might use multiple browsers
(especially the embedded browsers on mobile devices)... even taking all
that into account, a factor of four seems like a large disparity between
this data and the audience panel numbers.
