I think the advantages of A2xx starting hands are they are going to do well expecially when a low flop comes, even more in multiway pots.
And if you have nut low after flop, it's less likely to be upgraded in favor of the opponent unless A or 2 comes, while with high hands it is more complicated and player in position can use it to create some pressure, for example you flop straight and turn/river open flush or fullhouse possibilities for the opponents, so you are not sure where you stand anymore.
Of course calling too much with just a draw to low might be a road to hell very often
Particularly when I chose to play plo8 cash game at times, it was also because it was easier to earn rake/points in rooms with rake type "dealt", because there are bigger pots. Normal plo is more straighforward, although the power of position is bigger there than in plo8 I think.

A good high and low hand is less valuable as you're usually only going to get a split . This isn't really as profitable as it appears on it's surface.
Playing a low only is somewhat of a suicide run. Though... you do see good players laying on A2 hard. The reasoning is that if the make the nut low they can bet with impunity, and they might be able to bet the high off their hand. Resulting in a scoop. Scooping is the goal in PLO8.
