I believe this is just referring to the glucose:fructose ratio now being closer to 1:1 than what it used to be. In the old days people only looked at glucose and the 60g/hr limit is more or less for that metabolic pathway. Fructose takes a different path so you can easily go to 120g if you are using a 1:1 mix. Also the old 60g/hr limit isn’t universal so that is how you get some people that can handle 150g+

Just adding my own info here:

When I rode, years ago, my intake was ~110g/hr during 100mi+ rides. This was with the GU brand gels which is a mixture primarily compose of maltodextrin and fructose.
