I'd say yes; at least that was my line of thinking when I read the
note.  I took it as another clue (in addition to the use of the
moniker "Dark Lord") that the writer was a Death Eater: Often people
who work together address and sign communications with their initials,
and this person clearly expected Voldemort to recognize his (or hers).
