I would set up the die, make sure it was making perfect points and then turn it over to him for the mundane task of working the handle.
An awful lot of bullet makers do this. It's probably all right as long as the handle-puller is consistent, and both capable & willing to learn.
For example, Jef Fowler sipped whiskey while the handle was being pulled -- because he didn't pull it. Believe Clay Spenser's daughter put herself through school making Spenser bullets. The 103 6mm is an awfully good bullet, and I know more than one long-range shooter who worried when she got married. Fortunately, the family's still at it...
On the other hand, R.G. Robinett pulls the point-up handle himself. Believe he'll let Donna seat cores, but he insists on doing the pointup operation. His reason is, you can feel things through the handle in pointing up, so a BIBs bullet that doesn't "feel right" when pointed doesn't make it into the box.
Doesn't mean it takes the name behind the bullets to do a good job. That's where the "willing & capable of learning" comes in. Best is to find a smart person with a tolerance for repetitive tasks. I always figured the best pointer would be, say, a musician with great sensitivity in their hands who was borderline compulsive (the "borderline" part keeps them out of the hospital).
What's special about Berger as a large-scale manufacturer (at least as of 2005) was that they developed some sensing apparatus for the hydraulic presses. It may or may not rival the feel" of a long-time bullet maker, couldn't say. But the "capable of repetitive tasks" part is down pat.
