I think his point is that while the ultra races may be "easier" for those who only want to complete within the time limit, they aren't easier for those who are actually racing them, or even who are just trying to complete them as fast as they personally can.
That is a heck of a lot more specific than the rather vague comment you are translating from! God bless you for trying though ...
But still, who the hell can know? 10 day race, even if you're aiming for the podium, requires very careful pacing; vs a 300km audax, which the same rider might ride much closer to flat-out. That's just an example of how there are way too many variables. OK, here's another one:
we see "Ultra races" that are well under 1000km. I know from riding 600km+ in a race that doing a 1500km audax event took a lot more out of me.
As I said, too may variables ...
