Fuji Apples

When we purchased mature fruit trees, one in particular we wanted was a delicious Fuji Apple. The nursery advised us that we would have fruit bearing the first year. Well, I have since found out that this is not the case at all.
As we observed the tree grow this Spring and into the early Summer, we noticed that there wasn't a hint of fruit. After questioning the nursery, we are now being advised that it takes 3-4 years for a Fuji to bear fruit AND only if the limbs are hanging downward (pointed towards the ground). Story changes quickly once the sale is made!
Furthermore, we are now being advised that in order to get the branches of a Fuji to hang downward, we have to place some device (string and a weight, or similar) to the branches to force the downward growth of the limb., which will then allow fruit (in a few years).
I am an amateur and don't know this to be totally true but maybe some one reading this is educated about Fuji's.. If you are, comments are appreciated.
Thanks and happy growing.
