So why does it have "08L" at the west end and "26R" at the east end? It
may not be a very good runway, but it IS a runway, and is shown as such
on pilots' charts.

It's best to describe it as an alternate runway, not a second runway.

Successive flights alternate between them ?

No. The "taxiway" runway is an alternative to the normal one when the
latter is closed for some reason.
