I can't see how they could be used to feedback any signal for neutralisation
C13 and C7 form a capacitive voltage divider, which actually doesn't divide by very much! So will 'force' 89% of the RF voltage at the right-hand terminal of C7 (the top end of L6, which you'll notice has deliberately-added resistance before meeting with the 'quiet' HT) to appear on the non-earthy terminal of C13.
