Not a Geologist Chesh, but originally they may have assessed that Tai 3 was giving them all the options through Intra Lake Beds, Base Lake Beds, Top Karoo, Karoo Sst, and finally to Basement at 1100m TD, with multiple chances of obtaining the free gas we all wanted.
After having to go another 350 metres to reach basement, with increasing difficulty, and finding the concentrations improved the deeper they went, you would have to assume they surmised that the basement might be their best chance of success.
So, they needed the drill fixed and smaller drill and strings to carry on at Tai 3, so the obvious thing to do while waiting for all the equipment, is to go and Drill straight to basement at the shallowest point you can find, hence tweaking the Pad to a different location at Itumbula.
That's how I see it, anyway!
