The funny thing is, their own examples demonstrate (quite well) the conventional definition of DOF.
the luminous lasnscape article says that it is a myth that wider lenses have more DOF, but you have to read the conditions imposed: the significant caveat is stated clearly:
if the subject image size remains the same
In order for the subject image to stay the same size, you have to move closer.
DOF is reduced with a) longer focal lengths, b) wider apertures, and c) closer focusing distance.
Wide angle lenses do have greater DOF (this is NOT a myth) when compared to a longer lens shot taken from the same spot, (but not when you move closer to the subject in order to keep the subject size the same as in the longer lens shot.)
