It may be true of pro riders, but it's simply not the way that ordinary people use bicycles.

The saddle pain they describe is caused by too much pressure on too small of an area--and as for the "arms supporting weight" business--that leads right into the numb-hands problem.

And it doesn't exactly wash with pro riders either: if your rear-end (on a bicycle) was under less pressure than it would be sitting on a normal chair--then your choice of bicycle saddles should be even LESS particular than of chairs. But that's not how it is now, is it? You could pick any three major saddle companies and they'd probably have at least ten seats each on the market--but Park Tool only makes one shop stool, and it doesn't look anything like a bicycle saddle.

You an minimize riding pain on an upright bicycle, but you can't ever eliminate it.
