If I read this correctly, then this means that for some software packages,
multiple bitbake recipes exist for the purpose of breaking dependency cycles?

How does the generation of build order work? Which algorithm handles the
selection of recipes such that build dependency cycles are avoided? And once a
recipe which was used to break a dependency cycle was compiled, how is the
recompilation of the *full* package scheduled?
