This is not necessarily true, the DOS and the sum of all PDOS are not the same thing (do 
you know the difference between the two?).
They biggest differences are above the Fermi energy, but some differences can be present 
also below.
The "spilling factor" at the end of the output from projwfc.x gives you a measure of this.

Try to browse the forum archives to get something more about this topic, I believe it has 
been discussed many times.
