I see your issue with this recipe, and I spent time studying it for the reason you mentioned. The instructions say to let it go to <1.000, then rack into a carboy. But usually instructions for racking into a carboy, or leaving it in the primary for extended maceration, say to do it at around 1.01 so that the remaining fermentation creates a CO2 environment, pushing out any oxygen. In the times I've made it, I've never let it go to 1.000 before doing something to trap the CO2. At around 1.010, I've either snapped the lid down and let it finish in the primary, or racked it into a carboy and let it finish there. It's easier to do it in the primary, so that's the way I've settled on. It's so cheap and fast to make that you can try it many ways in the time it takes to do a "proper" wine from a kit.
