Sure. Since Alice's shadow DOM subtree is added later than Bob's, his
tree is older than hers. The way shadow insertion point works, it
looks for an older tree in the tree stack, hosted by the <ul> element.
In this case, the older tree is Bob's. Thus, Bob's entire shadow DOM
tree is inserted in place of the <shadow> element. Does that make more
sense? What can I do to improve the example? A diagram perhaps? Please
file a bug with ideas.

In this particular case, since both Bob and Alice use
DOMContentLoaded, FOUC is not an issue. The first paint will occur
after the shadow subtrees are in place.
