The 3 to 12 inch piece of limb that you see still attached in the pictures will rot and prevent a callus from forming over the wound to protect the tree.
Even if you are not a tree expert you can tell that the the way the tree service left the limbs do not look neat and clean. The reality is that over time these will decay. The picture with the yellow leaves shows a branch trimmed even farther back in time. This branch in the center of the picture has started to decay at the end. This can eventually work its way back to the main part of the tree.
