Yes, that's the idea. Ideally, if the tube is up in the tire, far away from the bead, then it causes fewer problems. You don't want it interfering with placing the "other" bead close to the center channel, and of course you don't want it near the part of the bead that you are working to slide over the rim. But it's hard to get it to stay out of the way, particularly near the valve, and this makes it harder to pull the bead into the rim channel to produce enough slack..
