Torroid Wrapping schematic confusion

Hi guys and gals, I am working on expanding my gear and upgrading license to allow more bands which involves buying a couple kits to learn and play with. I bought an ATU kit, however I am hitting a block on the torroid wrapping info on the schematic:

Schematic: http://ift.tt/2fTkY06 (confusing part is circled on the breakout and main schematic). This core goes into a 12-choice switch via the taps

I watched a youtube video or two and also have looked online about this. They all mention the 12 different “legs”. But I see this arrow on the diagram and never seen that before on a schematic.. Can anyone help me decipher it? (Around 3 2 4 turn area).. I otherwise understood most of the schematic, but when getting to the torroid I am hitting a block, the smaller one from the SWR meter component is obvious..

Am I correct in thinking to wrap as normal, and just do each turn # and then leg and then its saying other end goes to GND. Or do I switch directions? The instructions say follow schematic.. and the videos have not shown or mentioned the complete process of turning.

Thanks for the help!! I go for my upgrade this coming Sat, and am ready to get on my new QRP rigs and face the challenge of low power comms once I get this figured out and my antenna built!

edit: more details
