It means that the +12V rail is split up into 4 outputs. It's another safety mechanism and you never have to worry about it except for extreme dual GPU cards like the R9 295x2 (in that case you want to have one 8 pin connector from one +12V rail and the second 8 pin connector from a different +12V rail).
