Wikipedia has a diagram even:
Also, most fruit isn't pure fructose. There's a significant amount of glucose, either free or in the form of sucrose (or, in the case of bananas, starch). And glucose most surely does replenish muscle glycogen stores.
Liver glycogen is depleted by not eating. Any time when you're not digesting a meal, up until about 12 hours of fasting, you're fueled by liver glycogen. As the muscles start to take up blood glucose to replenish themselves, liver glycogen will be providing whatever glucose isn't coming in from food.
