That is as good way to explain it.
If the pivot point is closer t the rear of the boat then the lever action of the prop walk and even rudder control is much smaller than the lever action of the wind on the bow which has a longer lever.

There is an amplification effect also when going in reverse.
It feels like what happens when you are trying to backup a trailer with a long extension. If you get off just a little it rapidly causes your heading to go off.

It would be very useful to be able to mentally calculate all this and be able to successfully back down a fairway even if it was at a bit of an angle.

The lesson from the Icarus story is not about human failing.
It is a lesson about the limitations of wax as an adhesive.
If you have an engineering problem solve it.
