I could be wrong, but I thought that the straight bead offers more surface area for the tire and sealant to maintain an airtight seal, even under more sidewall deformation found at lower pressures. Or, that the angles involved with the sidewall going straight into the bead rather than in a big curve offers better burp protection.
