The difference between the first bead and the second is that there's the opposite bead and tube conspiring to push the second bead out of the groove. Two suggestions.
1. After starting the second bead, stuff a length of 1/4 inch nylon tube between the rim and bead to ensure the bead isn't being pushed out of the groove. Not usually necessary, but you have presented a worst case. 2. Since the valve stem fills the groove, leave the valve stem as the last place to push on the bead. Also, if you have to use a tool for the final push, the reinforcement of the tube at the stem and ability to push the stem into the tire may make it a bit easier to avoid pinching the tube.
