I'm sure I remember something similar coming up on chrons years ago, and it really was a good way to highlight the difference in POV approaches.
This is especially the case when in close third, where you want as much of the experience to be subjective - hence the need to cut down on phrasing that creates distance from the POV.
For example:
"He saw the cat was on the mat."
If we're in that character's POV, then "he saw" takes us out of the subjective and into the objective. But if written as:
"The cat was on the mat."
then we're still in the subjective experience.
I know Jo Zebedee has especially made a point about this before, so it's nice to revisit the subject and better understand why it makes more sense.
