I hadn't considered the degenerate case. However, if one looks at the
key selling points for orphan mode, in the documentaion, one finds that
they all depend on having multiple orphans at the same stratum:

If it really has benefits in contexts where there is only one orphan
mode server, the documentation needs amending to mention them.
Note two orphans at the same stratum aren't possible here, as the
requirement included a strict precedence and two at different strata is
another degenerate case.
