They actually keep the pad sort of in place. If you have ever installed the pads without the "ears", you will find out that the pad is free to fully slide inside the caliper and can drop all the way towards the center of the rotor. If the pad has "ears", then it will more or less stay in the same place and will align with the retaining pin much easier.
