Misaligning of semibreves in different voices.

See the attached image. I can understand that Dorico does this because of rules about notes with stems, but there’s no need for it with stemless notes?

Obviously, the solution is to change the voices.

In contrapuntal music, two voices with semibreves might have crossed, and mis-aligning the note heads is the only way to show that.

But as you say, the obvious solution is change the voices, or make a chord.
