It certainly does - so why do the specs say 'new internal coating'? A glass prism can only have an external coating. Unless they mean a new multilayer coating between the glass and the mirror deposition (the prism doesn't actually need mirror coating to function, but most prisms can be improved by mirrorizing the surfaces).
