Of course, you are using another extreme ... a 1.4 lens at wide open so almost 0 depth of field,
Wayne, agree, something needs to be extreme for this effect to be noticable, either a large swing or a narrow dof (and practically both).
Just out of interest I did the math for the OP, with a 100 mm f 2.2 on a MFDB
For that lens at 5 meter distance and full open the dof is roughly from 4,80 to 5,22 meter
Using the same formula a "swing" of 1,50 meter would result in the focus point actually being right at the edge of the dof. So if you're shooting a standing person and focus on his face and then swing to his (her) feet will just render the face oof, indeed quite extreme.
As you say, something to be aware of, but not something you need to lose sleep over in practice when you use "smaller" swings and close your aperture one or two stops for better sharpness and dof.
