The movement of sucrose from Mesophyll into companion cell

One common mistake students make is to mention sucrose's movement into companion cells is by active transport. It is not! It uses ATP indirectly for the pumping of protons, so it is called a secondary active transport.

Isn't it through facilitated diffusion? Since sucrose makes complex with H+ ions when they move from the mesophyl cells to companion cells.
