The 1962 18-wheeler that GM researchers came up with utilized this configuration,although the curvature of the cut-line is reversed to make the leading edge of the trailing structure a prolate hemisphere rather than a parachute as appears in your graphic.No matter the position of the "lead" structure,the air is always striking a radiused "nose" of the trailing structure,with no flow separation.
