It alerts you to the favored tack. The 1,000 mile away waypoint should be on the same bearing as the true wind direction.
And what I'm saying is that the waypoint above should *not* be based on wind direction, precisely because (as you mention) it isn't consistent. Instead, put the waypoint far above the line created by the upwind mark and downwind marks. You don't necessarily want the best upwind VMG (after all, if the wind shifted 60 degrees during your upwind run, making best upwind VMG would be a huge mistake!) What you want is the best VMG up the line to the mark. My waypoint placement will give you that, no matter where the wind is coming from.
As for your second waypoint. Yes a waypoint at the mark to help judge laylines is nice, but few GPS units will give you VMG toward two different waypoints at the same time.
