If it's both AS flights and you're on time, the second may be almost done boarding when you land, but as long as they don't screw around with getting the jetway aligned 11 times before they open the door, you'll probably make it. You can walk the length of T6 in a few minutes. I'd want to be sitting up front on the inbound if my connection was that short, and would generally prefer 40+ minutes. Depending on where you're coming from and the time of day, there's a reasonable chance you'll get in early - they block extra time for taxiing around and waiting for alleys to clear at both ends, and if you don't need them you could be up to 20 minutes early.

They also do often board early and do headcounts to try to push early - I've left the AS Lounge at the official boarding time and gotten to the gate in less than 5 minutes to see them anywhere from not started boarding to halfway through group 5. If it's a single PNR they'll know you're on the way, but they may or may not care.
