That’s pretty much required for their to be any structure to the joint, but having that big flag on there pushes the shoulder very far away. If it wiggles at all, it will split that off. I’d trim it back to the radius’ end.
Better still, cut them parallel to the leg, ending as the radii terminate and make the tenon shoulders at an angle.
Angled joints have many structural advantages but a practical cutout disadvantage is that the mortise depth is very difficult to make matching the angle of the leg, inevitably it’s shorter at the bottom.
