The phone will actually perform better being bent this way as the distribution of stresses goes from pure torque (compression on top, stretching on the bottom) in the middle (where the load is applied) to pure shear at the edges where it is supported.
The iPhone6 has a weak spot for torque at about 1/3 of the way from the top where there are some buttons. This test didn't stress that as aggressively as it could have. I suspect that it would perform 20-30% worse if you loaded it at the weak point.
The real issue here is that the phone both grew in length and was reduced in strength at the same time. That means that actions which previously didn't approach the elastic deformation limit of the phone now are. No change in behavior => change in result especially one with negative outcomes is going to get people riled up.
