Restarting before landing is a settable parameter on some ALES units.
Probably the most popular ALES unit, the CAM from Soaring Circuits, will allow a restart once you get below launch height. That, at least is the default setting. I don't know if it can be set to prevent restart.
One of the reasons our club standardized on the CAM was because you could relight. Better to save the plane and take a zero then have half the club in the woods looking for planes or trying to get them out of trees.
It is my understanding that some of the others will not allow relight and some can be set.
I won't be at the ALES XC a the NATs so my comments don't count. But I would vote for allowing a relight with the understanding that you take a zero for the flight, whatever a zero means in XC.
