That way if the back looses grip, you can drift it and correct it. If the front looses grip, you're going down, unless you're very skilled/lucky and get a 2-wheel drift going (though you'd still want the back to go first).+1
I used to run a 2.5 on the front of my old bike and a 2.2 on the rear (due to clearance issues), no problems at all. The only time I've put a smaller on the front than the rear was with a mud spike, where the narrower tyre can slice in and bite the ground better (other surfaces you don't need that, so you want a larger surface area to cling to the more solid ground). The other advantage of putting the less grippy tyre on the back is the rolling resistance is lower, so it's easier to pedal.
Ask a racer of any discipline and they'll tell you the same thing.
