A mistake in El Hazard?

[dikpierce]

I've just recently been hooked on this new drug called 'anime' and while watching El Hazard for the first time I noticed something strange. I watched The Magnificent world + ova's and it said that Makoto was transported by Ifurita with the last of her power. I then watched The Alternative World and it gave refrence to Makoto arriving to El Hazard via school project. He arrived to El Hazard in The Wanderers by Jinnai messing with his project. I thought the first two had nothing to do with the TV release?
Any one else seen this series and could shed some light on this for me? Thanks.

Just viewed Full Metal Panic! and Saikano. Next in line is Martain Successor Nadesico.
