Use method A or B to repeatedly switch pieces (1) and (2)

We gave Marcus a Rubik's Cube for Christmas. Elf had passed on to him a little logo-bedecked giveaway version a few weeks back, and he has spent many happy hours swivelling it about. He is pretty close to getting one layer all in the right places. The new one comes with instructions, which although clearer than those for the Teased Pearl Marble game, do not fill you with confidence. I jumped to the end to see how to deliver the coup de grace to the cube, and found this advice.

If the third layer's center pieces are not in their proper positions and facing properly, use first pattern A8 and then pattern B from step 5, except that sub-steps A8 and B8 should be changed to 90%.
