At one point there were about 30 passengers onboard - this is far more than I have seen on a daytime, never mind an evening journey.

Does anyone know if this fare offer is going to continue? Surely it would be advantageous to continue, as usually the evening Coaster services would rarely get into double figures?

I'd hope it would continue.
Businesses have been built on the low fare model and it works for them.
I've argued many a time, that a lower fare could attract more punters. There are various theories and models which show it can work and from what you have said, what GNE are reporting and. From what I've seen - it wouldn't make much sense to drop the scheme. It would be incredibly short sighted imo. 
30 people paying £1 is a lot better than 5 people paying a couple of pound.
