when i pay off my mortgage loan, what would really happen?

the underlying investment is usually somewhat independent of your mortgage, since it encompasses a bundle of mortgages, and not only yours. it works similarly to a fund. when, you pay off the old mortgage while re-financing, the fund receives the outstanding debt in from of cash, which can be used to buy new mortgages.
