The difference with a bonsai mum is that she's already happily vegging, her hormones are nice and steady and appropriate to a plant who will live indefinitely in veg. Basically, there is nothing telling her that she SHOULD be dying off right now.

With re-vegging a mom, my goal is to keep all other conditions STABLE and gently coax her into reverting to a vegetative state. I want her to not be producing any more flowering hormones. I am sure to go over the plant and remove ALL seeds, including unripe ones. Any other chopping up is a potential stressor so I avoid it.
