What is the purpose of the graphite applied inside the metal-graphite wound gasket?
It’s the graphite strips added inside the steel strip; they’ve been in use for many years now. There’s no need to worry about them, as the sealing effect is quite good.
Applying graphite mainly serves to fix things in place, preventing the gasket from shifting, and it has no effect on sealing.

It’s not wiped on; it’s a flexible graphite strip that serves as a seal. Applying graphite powder, molybdenum disulfide, copper powder or iron powder, as well as grease to the sealing surface was once said to be able to compensate for minor defects in the surface, but this practice is no longer recommended.
Without graphite strips, it’s just powder; you’ll know once you peel back the layers of the gasket
