Both sucrose and HFSC must make it to the small intestine to be metabolized, the only difference is the chemical bond is broken by sucrase in the intestinal wall. Both are metabolized quickly and into the same components in the bloodstream.

I am still not seeing the difference?

edit

Perhaps I misunderstood what you meant by "unbound" I thought you where referring to the chemical bond in sucrose, vs being bound up physically with fiber in fruit.
