Ionic radii of transition metal ions in the presence of weak field and strong field ligands

‎‎‎‎‎‎‎‎‎
In the graph given in this image,‎ I was told by my teacher‎ that whenever we start filling the eg orbitals there is an increase in the radius because these orbitals face the ligand directly and hence the repulsion causes the radius to increase.‎
However, my reasoning says that due to ligand repulsion to electron cloud of that eg orbital, the size should rather decrease. I am confused‎
Is what Sir said true? help me in comprehending this.‎
