Well, it seems to match the routing model of source routing, but I would
like to know for sure, as I'm not very familiar with source routing.

By specifying a maximum loop count, as it is with symlinks.
Isn't the Source Routing option (for IPv4) limited in size? There would
be no point in having more loops than this limit.
