Try it. It'll only take a few moments a day and may help.
And maybe try speedreading too.
I have no experience with this, so I'm just guessing here, but maybe if he read faster he would be fully occupied and better able to concentrate without drifting off.
If the problem is lack of concentration then it seems to me that trying to do 2 things at once is just adding to the problem, not solving it.
