I assume this is a general example of a situation where you have to run
LaTeX multiple times, and not something applicable to Org's LaTeX
previews.

Was this for in-buffer previews or a LaTeX source block?  Could you
provide the LaTeX source for a minimal example?  I'd like to try it with
the new preview system.
