Sony US26650VT Li-ion Cells - Need More info

Alright, were the 4 bottom cells come together in the middle. the purple line that is connecting the cells, looks like its connecting all 4 ends together. In other words both cells would have there negative ends soldered together as well as the other cells possitive ends. Except wouldnt that short the cells? Make sense? I know im terrible at explaining things. :P
