In blue blazes they know that 20w50 oil pumps like 20w when cold (read that as better than 30w) and like 50w when hot. As Allan properly noted above, all oil runs "like water" when hot. If you carefully measure it, however, 50w hot is thicker than 30w hot but may not be much different than cold water.

20w50 is not a fix for a bad bearing but with moderate engine wear, changing to 20w50 can extend engine like by offering better oil pressure to keep loose parts lubricated.

It is true that 20w50 can mask only one bearing dumping all the oil but even 50w hot oil will not show good oil pressure in a very worn engine.
