Eric,
Hope you don't mind me using the quote for this response.
My concern, though, would be that the center post is much more heavily loaded than the perimeter posts/supports and, if the center footing is not sufficiently larger to account for this increased loading, that the center support, and thus the center of the deck, could settle un-equally with (settle more than) the perimeter, leading to cracked and / popping tiles as the flat deck surface become no longer 'flat'.
