What's the benefit of cutting borders on the bias?
I might be understanding the question wrong but it's not cutting the whole border out on the bias just the seam if you have to piece the border. I feel like the seam is hidden better when you join with a bias.
I think your understanding is good. What you say makes sense. And I agree. It depends on the border fabric...some look fine on the straight cut seam but most look better with the bias cut seam.
