I have a doubt here.

$ grep -rI 'setscene[[]depends[]]'
bitbake/lib/bb/tests/runqueue-tests/recipes/d1.bb:do_package_setscene[depends] = "a1:do_populate_sysroot_setscene"
bitbake/lib/bb/runqueue.py:    # e.g. do_sometask_setscene[depends] = "targetname:do_someothertask_setscene"
meta/classes/useradd.bbclass:do_package_setscene[depends] += "${USERADDSETSCENEDEPS}"
meta/classes/useradd.bbclass:do_populate_sysroot_setscene[depends] += "${USERADDSETSCENEDEPS}"
meta/recipes-core/sysvinit/sysvinit_3.14.bb:do_package_setscene[depends] = "${MLPREFIX}base-passwd:do_populate_sysroot"

useradd.bbclass with USERADDSETSCENEDEPS also resolves into depending on setscene tasks.

So tests and useradd depend on setscene which is also documented and handled in requeue.
To me it looks like sysvinit (where this fix for pseudo was presumable coped from) uses wrong task dependency which works only by chance.
But this is deep bitbake stuff which may have special nuances.
What is the difference between using these two variants?
