I suggest you try it, and you'll see that you guessed wrong.

@ doesn't set a new origin, $ORIGIN does.  @ is simply a special token 
that gets replaced with the current origin.

When you begin a record with blank space, it means that it uses the 
owner name from the previous line.  So:

mail02 IN A 192.168.x.x
  IN MX 10 mcvpemr01
  IN MX 10 mcvpemr02

is equivalent to:

mail02 IN A 192.168.x.x
mail02 IN MX 10 mcvpemr01
mail02 IN MX 10 mcvpemr02
