Some spells will auto target when forced, as Handnavi has mentioned. Other spells are actually done by superbad without targeting. For example if you enable taunt, the routine will taunt mobs without actually targetting them.
Your log, you most likely started the combat by hand either auto attacking or using any spell on the dummy. All the time that you are in combat, superbad will try to force spell usage regardless of you clicking off the target. If you click off (or press escape) fast enough and many times, superbad will actually time out of forcing the combat. The reason why Swipe or Savage Defense or Enrage dont target the dummy is because these skills dont require a target, you can freecast them even out of combat. But every other spell that is used and forces a target like Maul Mangle and Lacerate will actually require a valid target...
Regardless, turning off the targeting option is great for maintaining a focus target in mulitiple mob situation. If your character position is favourable, the routine will dot any other mobs without targeting them. At least for me with Raidbot it works that way. On galakras every add has a ferie fire debuff on them even though i only focus the bonecrushers

and anything close to the bonecrushers has a rake dot on it.
