This is specific for the conventional nailing technique.

And it could be even more medial.

As i mentioned a small wire distractor was used. In common upper fractures it is enough to insert 2 frontal wires to the proximal fragment - one in the upper posterior aspect of the tibia and the second anteriorly and a bit more distally. The technique allows to avoid such known tricks like more lateral entry point, semi-extended knee, extended approach, using of bone clamps, plating with monocortical screws etc.
In this particlar case 4 frontal wires were inserted in anterior and posterior aspects at both sides of proximal fracture, and fixed to a single half ring with some bend to provide compression with wire tension. Image attached.

You are absolutely right, and the entry point could be more anterior without the risk of angulation. This a bit posterior placement was caused by the proximal anterior wire. No obvious problem with the knee though.
