If you trail the blade, I think the pressure, however great or slight, will be focused on the spine of the blade, making the trailing edge run across the stone more lightly. That has it obvious advantages at higher grits, but for doing shaping or repair work, it would be slower. This method could also backfire by inadvertently raising the edge off of the stone as you make passes. There is also the argument out there that trailing the blade pulls the burr forward, helping it to remain "straighter".
By leading the blade, you put more pressure on the edge of the blade, which better ensures the edge comes into contact, and remains in contact with the stone. The biggest sharpening threat is rolling the blade by inadvertently raising the spine off the stone. Personally, I think leading helps to "clear out" the burr because it gets caught in the hollow ground area of the blade as it comes loose, rather than pulling it out from underneath.
On a safety thought, trailing the blade is safer because you are never moving the blade towards your body - especially your fingers.:chop:
This is probably the best and biggest argument in favor of trailing, not so much the technical or analytical reasoning. You don't want a shave from a bloody barber, or one with only 8 1/2 fingers.
Of course there is lots of room for argument over personal techniques sharpening, and I do still have 10 fingers (and 10 toes):D.
