I suspect that in the first link, the "full economy" reference refers to 1 point per mile in BHY as opposed to 1 point per 4 miles for the other classes, it is in the 'Airline Earning Table' after all.
Perhaps they should set-up a standard table, dealing with both points earning and SC earning in the one.
Try and push the point though, tell them you booked in that class specifically to get the SC's, you could have got it a lot cheaper, that you paid more based upon the misleading information on THEIR website. You never know until you try it.
