grip and how it is formed by a cpecific archer is all about torque and how still the bow holds (erica is right and as she says this is also done with stabilsers). What the bow does after u have pressed the trigger or let go of the string.... Who cares.
Bows that shoot tens have great reactions as far as the archer is concerned
This can only be achieved by good balance and reduced torque at full draw and this is what the grip does.... and stabilisers.
One can shoot round any problem of grip or balance but when a certain level of pressure is exerted the performance will fail
