Newbie question... Why does this company run SD-WAN over MPLS?

I recently got hired as a contractor at a large corperation to do minor networking stuff. I am studying to become a Network Admin so I am still learning a lot. They have a bunch of branch offices that use ATT MPLS circuits. But they are in the process of converting to SDWAN. They are using 2 VCEs, one is using a broadband connection, and the other is using the same MPLS circuit. Why would they do this? I thought SD-WAN is supposed to just run over broadband internet... Wouldnt their goal be to get away from MPLS? I asked one of the full time engineers and didnt really answer me... so I thought I would ask here.
