I understand that on bottom brackets that have different threads on different sides "Left <-> Right" mark has its meaning. But why is it also stamped on standard Shimano UN 52 italian bottom bracket, which has same right-hand threads on both sides? Is there any reason why it should not be installed the opposite way?

The "fixed" side of the BB goes to the side of the chainrings (right).

Some frame makers assume that a cartridge BB with a flange only on the right side will be used, and only square off the right side of the BB shell. (Of course, some don't even do that much.)
