New player, wondering about grappling and ramming

I've noticed grappling and ramming are often used in the same sentence. Titanomachy Mesh gives a free action to do either on a successful grapple or ram, for instance.

I'm wondering what the use is for grappling multiple times. On a successful grapple Mesh allows another, but at that point you already have the benefits from the first. If I choose to Ram instead, the resulting knockback would just result in breaking the grapple. Likewise, if I use Ram to knockback a target, it would be out of reach for grappling.

Is the use case for Titanomachy Mesh purely to get a target grappled and prone in the same turn?
