Cuz, like I said, walking in the core seems to imply spending some time in the area with the highest temp and gravitational forces of a red sun.

they flew through it at something approaching lightspeed.

i think OV was just trying to point out that Red Sun has been portrayed as having a gradual effect on Superman, so it really depends on how much time we're talking about.
