C2/Twinkle McNugget, do you have a reference for this because I don't see anything anywhere that can confirm. If you look at the Combat page on Stratics it's pretty clear and on the Anatomy page there is mention of Anatomy coupled with Eval making you harder to hit or, of course, Anat being an essential part of Healing. But I can't find anything that discusses a bonus when having both Tactics and Anatomy.
You certainly get the effects of both Anatomy and Tactics if you have both skills however it's a cumulative bonus based on the skills themselves giving a percentage of base damage as a damage increase modifier, there is no bonus for having both above and beyond the base modifier for each skill.
