I don't think it matters as much for large corms if the root structure remains intact, but if you want root structure to grow from the corm, the corm must seek out water. When you deny them water they are forced to root further away from the plant.

With regards to pups, the wound needs time to harden before watering. Some people don't even plant the corms for several days so the wound can dry out.

I have experimented with freshly cut pups and watering. Pups that I watered directly after they were cut wilted and took months to recover. The pups I didn't water remained flaccid and did excellent.
