I meant sync to it, of course.

In my experience, they won't. (I have this configuration at home, with
six leaf nodes. I'm not claiming proof, but it's a _lot_ of anecdotal
evidence.)

The backup is normally synced to the primary. So its stratum is one
higher, its root dispersion is higher, it's less attractive in many
respects. Perhaps the leaf nodes even recognise that one server is
in the other's sync path and disqualify the latter for it.
