Actually you said it would be "replaced by body fat being used up" - not for replenishment.
"Being used up" may have been a poor choice of words but certainly implies being burned during intense (glycogen depleting) exercise. I disagree. I still believe that the only way fat will replace glycogen as fuel is if the level of intensity drops. Even you concede that fat can't fuel high intensity exercise so I'm not sure what we're debating.
If you're not OK with that we'll simply have to agree to disagree.
