I think it must be a typo. because 10.2.0.0/8 is not a valid subnet mask. The largest subnet you can make starting with 10.2.0.0 is 10.2.0.0/15.

It's still a valid subnet notation, the 2 just doesn't mean anything.

When you take the logical AND of the IP and the expanded mask, you'll just end up with 10.0.0.0 as the network address and 10.255.255.255 as the broadcast address.
