Imagine Dig like with Trevenant, a ghost type would need to dig like a normal pokemon does? no i t could disappear /phase through into the ground without making a hole in the ground, like going through wallls and then come up in a hole.
Hope more grass/ghost get dig done right this way especially if it based on something that "burrows" in the ground.
