I don't like twisted seams. I don't think long-armers do, either.
If it is absolutely unavoidable, I will clip the seam so it lays flat. I clip one side of the seam in another place and the other side in another spot.
My line of thinking is that I'm making only one side of the fabric "vulnerable" at a time. But the reality may be that I'm making two spots "vulnerable" instead of only one.
Then I put Fray Chek on the clipped spots.
