Yes, I've observed this too.

The "Sunny sixteen" rule dictates 1/ASA at f/16 for Bright Sun with
distinct shadows, and 1/125 is within 1/4 stop.  Since print film has
considerably more latitute than slide film, and prefers to be overexposed
(denser negative) than underexposed, it makes sense that Kodak would
"fudge" the print film table towards one stop of over-exposure.
