This is incorrect. Every contact closure in the vintage Hammond manuals for
a given tonewheel lowers the resistance in the path from that tonewheel.
Therefore, if one pulls the same registration on each manual and then plays
the same chord on both manuals the volume is louder then when one manual is
played alone.
It also follows that if you play middle and tenor C with the 8' and 4'
drawbars pulled you will hear a total of 3 tonewheel pitches and of these
low, middle, and high pitches the middle one will be accentuated since it's
passing through contacts on BOTH keys, were as the high one is only played
via middle C and the low on is only played via tenor C.
There is an answer for the "shrill factor" but I think you know what I would
suggest ^_^
Cheers!
