UPDATE
My fold-up stand is like the photo on the left. A tandem friend of mine has a stand like the photo on the right. Recently I was able to compare the two.
My fold up stand (on the left) definitely allows the bike to wobble from side-to-side more than my friend's stand (on the right). The arm that pushes against the wheel flexes. However, ultimately they both tip over at about the same point. In my mind, it's a question of whether you prefer the portability of the fold-up stand on the left or the added rigidity of the stand on the right.
