1 e4  is a single ply, 1...e5 is an additional ply
White played 1 and Black played 1, this is 2 ply together but for 1 single game
move.  So when you are talking about a depth of 6 ply it is 3 full moves while 6
would be 12 ply.  It can be confusing if books use it incorrectly i have seen it
happen.
