Miraak took many years to obtain the condition for the power to escape Hermaeus Mora. The Last Dragonborn won the fight and absorbed Miraak's soul(s). Technically, there is no more actual battle to truly know how strong the Dragonborn will be after absorbing over 10 more souls of Dragons from Miraak. Even if you make it simple and assumed the LDB was equal, a little weaker or stronger than Miraak. The Dragonborn will still be roughly twice as strong after defeating Miraak.

A simple math of 1 Dragonborn + 1 Dragonborn = 2 Dragonborns worth of strength.

Dragonborn's fate, well Bethesda purposely leave it free for interpretation. Though looking at the fact that Miraak's solution to escape Hermaeus Mora was to make LDB strong enough before killing him and absorbing his soul to gain the power to escape while the LDB had absorb Miraak's soul instead...

Miraak+LDB = Can escape from Hermaeus Mora.

What difference is there with...

LDB + Miraak = being able to escape from Hermaeus Mora?
