Here is the T-symmetric position given by Saxe and Hoey. In their position, the UFL and RBD corners are in place, and the other three pairs are swapped. The "girdle" includes the three pairs that are swapped. Hence, there is an axis of symmetry along the UFL-RBD axis. The odd number of swaps is compensated by an odd number in the edges. The compensation is not required for corners only.
