Default Dihedral- not understanding plan instructions

Hi,
First, I should also state that I am not an experienced builder, pretty much still learning and have been stepping up the challenge with each kit. I do know what dihedral is. Am building a Page Supercub, and am ready to start framing the wings up. Here's what I'm not understanding; The left wing side of the plan, at the last rib states.. Brace here 3/4" for dihedral, build other wing flat.

Huh?? I'm missing something because that makes no sense to me right now. So how is the left wing built braced at 3/4" if ribs arent on the spars yet? It would seem that to brace the wing, the wing has to be built or there's nothing to brace. So let's say I add the ribs and then raise the last one 3/4" then build it out. When I go to join it to the wing joiner 'box' (its a one piece wing), it would seem that the left wing would be lopsided if everything else is built flat. This is the 2nd kit I've run across with this, (first one I just put it away, as it needed a wing built on an elevated building board, as it has a LOT of dihedral, I didnt understand how to do that either). Can some experienced builder please give me some idea how this works, as I'm not getting it. Eyeballing I'm not seeing any angles on the root or joiner ribs.

Would ask some other Page builders, but the kit has been out of production for so long that doubt anyone is watching those threads. Thanks! HM
