Yes you are wrong. The pokemon that battles get half of the full exp. If you have 1 pokemon holding an exp. share that pokemon gets the other half of the exp. (see below)
No matter what the experience gets cut in half and the big half goes to te one that battled. The rest of the experience gets divided by how many exp. shares you are using and given to those pokemon.
Here is an example:
Total exp. 2000 exp points, Empoleon gets 1000, Gyarados (w/exp. share) gets 1000
Total exp. 2000 exp points, Empoleon gets 1000, Gyarados and Drifloon (w/exp. share) each get 500
