I see it the exact opposite. If you are just trying to draw back off the 10 about a foot to shoot the 8 in the type right corner (which is probably the way you should be playing it particularly if you aren't a good player), there is very little that could go wrong. Draw a little too far, or accidentally hit the pocket points/rails, or even if the cue ball stops dead at the ten ball and doesn't draw back at all, and you still have a pretty decent shot on the 8 ball almost no matter what (the eight will never be that far, and the cut angle will never be terribly bad). On the other hand lots of things can go wrong playing shape from the 10 to the 13, where you can get hooked by the 8, and where drawing too far or not far enough comes with much tougher penalties for the 13 in the form of a longer shot, or a tougher cut, or most likely both.
