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?

Some frame makers assume that a cartridge BB with a flange only on the
