Bear shot placement- vitals vs anchor

[Hardly_Hangin]

I recently shot my first black bear high shoulder with 165gr barns tsx federal premium ammo out of a 30-06 from 60 yards. Research would indicate that bears die quickly with well placed vital area shots, but are notoriously difficult to blood trail due to fat and hair. They can also curl up into hard to find balls of fur and tuck into inconspicuous holes, making it even harder to recover a dead animal. This shot effectively immobilized the 250lb sow by shattering both shoulders, and the bullets performed well by my estimation. However it did not flip the "off switch" and i had to humblingly dispatch, unpleasantly hearing the death moan from about 5ft.

Do bears have the same off switch? Is there a better shot placement location to "anchor" and mitigate risk of non-recovery? Did my bullet not perform? Did i miss the switch? Or- despite added blood trail difficulty associated with bears- are you aiming for vitals?
