I suppose anything is possible. As for there being two sheets, one for ILSAC 0w-30 and one for GC, there perhaps were, or they were filled with errors or minimums or maximums. Take a look at Shell. Formula Shell and Formula Shell Synthetic have the exact same spec sheet, except with the word "synthetic" added in. With Castrol (or most any other company), it wouldn't surprise me in the least to have had something totally bizarre on their sheet, perhaps having it the same as GC.
