For this case, I suggested using the existing pxref with two arguments (three
might be better still).

However, you're now adding another pxref and anchor, and the point I tried to
make above was that it shouldn't be necessary to have circular references
within a single node.

(Actually, as a rule of thumb, I would say it's a good idea not to have
references within one node at all, as it's not unreasonable to expect the
reader to, at least, skip read the whole node.  If it is unresonable then the
node is probably too long.  However, I'm not suggesting to take the first one
out too.)
