IMO, this is incorrect. The rule says when replay reverses a call to a running clock there is a RO. The rule says nothing about a 10RO if the ruling is not changed.
But this did lead me to find an editorial change I hadn’t seen. Two years ago, a rule was put in that a 10RO applied if replay created a running clock from a stopped clock (ie touchdown reversed to down inbounds short of the LTG). As of this year, it applies even going from running clock to running clock. So scenario:
1/20 @ B-40. Quarterback A11 scrambles in the backfield and then takes off downfield. He is ruled down at the B-22 with 47 seconds left in the half. Replay shows A11’s knee touched the ground at the B-45. In 2018 and 2019, this would not trigger a runoff because the clock was already running. In 2020 however, it does trigger a runoff because there was a reversal that led to a running clock and the previous clock status doesn’t matter.
