What is the reason for the square boring head that Criterion makes?
What advantage does it have over the round Criterion boring head?

You mean other than range, bar holder positions and versatility?
Turn the cutting edge 180° and what do you think can happen?
You now have an OD Turning tool.

Put the two of them side by side, what's the difference?
Item #4 is the hint, three set screws equals three tool positions.

Just be sure and use a rh boring tool or else the shank might come unscrewed

You got it backwards. The head might come unscrewed from the shank.

I think the reason they are still offered is some machinists think
they are more rigid than the round ones.

Sounds reasonable to me. A 3" square head has more sliding surface
contact area than a 3" round head.

With only one boring bar hole instead of three I would guess this
would also help.
