HRM says "If SSCAN2 bit in FMODE is set, then disable SH10 horizontal coincidence detect."
'Disable' means BOTH zero and one SH10 bit matches horizontal sprite comparator = same sprite can appear TWICE (horizontally) on screen. Without any copper tricks.
Fantastic Dizzy CD32 in Big6 compilation uses this feature to create background tree graphics, background is created using 4 x 64 pixel attached sprites.
