I read that twice and still couldn't follow it.

Basically, the main charging leads electrically ties the red wire of the middle pack to the rightmost black wire of the first pack, so the red balancer wire isn't needed. This is the "safe" hookup. If the user accidentally mixes up the balancer leads and main leads, nothing bad happens - it just won't balance.

You can tie the balancer red wire of the middle pack to the rightmost balancer black wire fine. That would probably look right to most people. However, if someone mixes up the balancer plug and the main leads, a short would happen and vaporize something. Removing the common balancer wire between each pack just adds a little safety.

True, a voltmeter on each cell could be used to make sure all the cells are equal, but what do you do if one cell is a little high? You'd have to load that cell down individually. Not to mention that this voltage check should be done often, particularly during the CV phase of the charge.
