Why doesn't the FIFO MegaWizard® allow me to use Showahead mode when I'm using a synchronous FIFO?

Environment

BUILT IN - ARTICLE INTRO SECOND COMPONENT
Description The dual-clock FIFO function does not currently support Showahead mode when using a synchronous FIFO. You are using a synchronous FIFO when the parameter CLOCKS_ARE_SYNCHRONIZED = "TRUE". This parameter is set to "TRUE" when you answer "Yes" to the "Do you want the FIFO to pipeline its output flags" question on page 3 of the FIFO MegaWizard.
