Setting you up based on the hoods makes sense - it's as far out in front of you as your hands will get. If you make that position comfortable, odds are all of the bar positions will be reasonably comfortable, which will allow you to make better use of the multiple positions, which in turn promotes hand comfort.
Sounds to me like your shop got it right, or at least pretty close to it.
