He certainly flew a slightly flat approach compared to what one would normally do in a light single. But perhaps in a Baron that's not such a bad idea? In something small it's easy to lose excess height without arriving dangerously fast by cutting the power and sideslipping a bit, but it's hard to gain any altitude at 7000ft once you are in the approach configuration - so a steep approach is safest. Perhaps in a heavy and powerful aircraft the same rules don't apply?
As for the point of no return, it is a dangerous concept in mountain flying. Firstly, you can't use a ground reference point, as head / tail wind conditions on approach will mean that the point where you can safely throw away the approach isn't fixed. Secondly, it tempts you to think "I'm a bit too high / low / fast / whatever but I can still go around if I haven't got it right by the time I pass that hotel" - when what you should be doing is concentrating on flying towards your aiming point at the correct speed and correct rate of descent, correcting any errors immediately. The point of no return should be the beginning of final approach, with the possible exception of the case where someone starts their takeoff while you're on final.
