Ah, you're referring to the first picture I posted a link to. You are correct, all four bottom cells are connected together in the middle there.
No short-circuits

. There would be a short if the positive ends of the bottom-left two cells were connected to the bottom-right two cells. Just remember that the two bottom-left cells are in parallel, as are the two bottom-right cells. So, 2p and 2p, and the top two cells are also in parallel, so add another 2p. All three of the 2p in series gives 3s2p

. If you need further clarification, just say so
