Dividing the diamond into two triangles is certainly a valid way to attack this. As with all things quilting, there are many ways to do it and different ways will work better for different people since we're all put together differently, too.
You don't really save yourself on the bias by dividing things into rectangles since that bias angle doesn't change. The biggest help to handling that bias, just talking about fabric direction and not other tricks like starch and freezer paper, is to align the long edge of the border with the selvage edge of the fabric to get the most stable grain along that long edge. So, each piece would be cut to match that alignment. But adding seams can make the construction easier in a couple of ways. First, it can make it more understandable which ends up being a very important factor. You definitely have to be able to see how it goes together before you can put it together! Secondly, it can provide opportunities to use larger pieces of fabric for the piecing and then trim the components down to the proper size to make the odd angles easier to get right. And there are probably other advantages that I'm not seeing right now.
I think it's great that you have the ability to break down the piecing and think of alternative ways to put things together to get what you want in the end! That's something that has taken a lot of practice for me and I'm often stumped with one of these problems until someone else shows me an easy solution!

Nancy, thank you for talking through this with me. I hope you can tolerate one more question/clarification....
If there was a diamond being cut out, wouldn't more of the edges be going in the direction of the bias? You'd want the length of the diamond, point to point, to be the part that parallels the selvage, right? But that would make every outside edge a bias edge, yes?
So if you halve that diamond into two triangles, couldn't you now make one side of the triangle the parallel edge and then gain at least one non-bias? If you did the yellow triangle that way, too, then the 2 edges that join the blue could both be straight of grain, couldn't they, and if so, wouldn't that help some?
Or is that just really not a good solution for cutting those pieces? You'd have to leave the blue so that the outside is straight of grain and the bias is where it joins the pink/yellow, so maybe you'd have to do the same on the yellow...but if even getting one edge of the pink to be a straight of grain wouldn't that help join the 3 pieces together? And then since the joined bits would be rectangles so doing a short seam there, wouldn't there be less stretching of the bias edges? Or not really?
I am following you, and I am learning, just trying to clarify in my mind in case I face this one day. Thank you for your patience in talking this through with me!
You could do that, but in the end you're in better shape if you have the entire length of the border following the most stable grain line of your fabric since that border is helping to contain your whole quilt. At least that's my opinion. (Remember that all opinions are valid and you need to pick the one that works best for you. Your choices are just as valid as anyone else's.)
And I tend to like to have as few seams as possible, as long as it doesn't make the piecing too difficult.
