Subject: Difference between PVS and NegaScout?

So what is the difference? I read that NS assumes that the score obtained when
D=1 or D=2 is the actual score even with null window? Could someone correct me?
Does this mean that in order to make PVS a NS you just add (Depth<2) to the
re-search IF statement?

if(Depth<2&&score>alpha&&score<beta)
   {...}                         // perform the research
