I'm not sure I buy that. If the they put the fork near the bottom, it seems like the compression would be the same, but spread over a longer section of the mast.
If the fork were at the bottom of the mast, the halyard would effectively exert twice as much compressive load on the mast (it would be 2:1), so the mast would bend more everytime you pulled the downhaul or mainsheet. You would have a very hard time getting enough luff or leech tension, especially in high wind. This would be exacerbated by the fact that the 20-something foot long extra length of halyard would stretch, so the sail would not remain at the very top of the mast. If you want to prove that to yourself, see what happens if you just tie off the halyard to the cleat without engaging the fork.
And of course, last but not least, bringing a conductive wire down to the mast base would negate the safety feature of the comptip.
