Well first of all this was meant more as a guide to how rather than why. There are loads of other discussions about why people are trying to avoid dunking. But in short pellets are no less food for bacteria as they are for pellets. When pellets remain dry in a bowl, they deteriorate slowly and can probably be left out for weeks. So a day or two is definitely fine with dry pellets. Water naturally has bacteria in it but it lacks the food for them to multiply excessively. Now add your parrots pellets to the mix. Those pellets are one of the most concentrated sources of nutrition and energy so when pellets meet water, bacteria will multiply rapidly and the water will go bad.
There is no reason for parrots not to learn to eat pellets dry. They are made to be eaten that way and once a parrot gets used to it, they love the crunchiness.
Finally, another major reason to employ the strategies I mentioned is for poop in water. Using a water bottle prevents the poop in water problem entirely. The other way is to offer water in the morning/evening (but only as long as it is acceptable for that species to drink sparingly) and take it away mid day. I do this when I take my birds away from home with me for any length of time.
I can't talk for all species, but my two pois definitely learned to eat a full meal of pellets first and then drink a lot to water it down after. Well Truman's actually the other way around, he prefers to drink first and then eat but the point is they don't go to the bottle more than twice a day.
