I'm pretty sure that at least some of the memory in it is non-volatile - e.g. the log survives a power cycle so if it "remembers" which upstream was used it's quite likely it will use that first to see if it can negotiate the same connection.

I can probably take a look to see if there's a pinhole but I've got it behind the settee (where the Superhub had to go to hide the light show)
