I will provide links to what I can get ahold of quickly.

For the "you can't destory Lorkhan's heart" bit

http://elderscrolls.wikia.com/wiki/The_Monomyth

""But when Trinimac and Auriel tried to destroy the Heart of Lorkhan it laughed at them. It said, "This Heart is the heart of the world, for one was made to satisfy the other.""

"Instead, The Nerevarine will strike the Heart with Keening for a second time, causing its tones to diverge into unstable patterns of interference. Further repeated strikes with Keening will further disrupt the tones, with the ultimate result of shattering and dispelling Kagrenac's original enchantments binding the Heart,"

The Heart being "immortal" is mentioned in the Monomyth, and nowhere in "the plan to defeat dagoth-ur" does it mention destorying the heart, only freeing it from its enchantments.

"Mind you, this story isn’t necessarily true, for no tale of Cyrus the Restless is true in its entire, and yet that has never really mattered. "

the story of cyrus's meeting with vivec, the only place the Pankratosword is mentioned even says "this story isn't true", and said technique has never been mentioned anywhere else, so sayigng that is what destoyred yokdua is suspect as best.

"The Underking arrives and is ambushed by Imperial guards. As he takes them on, Zurin Arctus uses a soulgem on him. With his last breath, the Underking's Heart roars a hole through the Battlemage's chest. In the end, everyone is dead, the Underking has reverted back to ash, and Tiber Septim strolls in to take the soulgem. When the Elder Council arrives, he tells them about the second attempt on his life, this time by his trusted battle mage, Zurin Arctus, who was attempting a coup. He has the dead guards celebrated as heroes, even the one who was blasted to ash... He warns Cyrodiil about the dangers within, but says he has a solution to the dangers without. The Mantella.

The Numidium, while not the god Tiber Septim and the Dwemer hoped for (the Underking was not exactly Lorkhan, after all), it does the job. After its work on Summerset Isle a new threat appears—a rotting undead wizard who controls the skies. He blows the Numidium apart. But it pounds him into the ground with its last flailings, leaving only a black splotch. The Mantella falls into the sea, seemingly forever."

The part in which the underking appears to destory Numidium takes place AFTER Ysmir has his soul taken, and after zurin Arctus took his place as the underking.

This also going into my "the mantella was used to power the numidium" as the text iself says "its not the god they hoped for, but it does the job" Meaning the mantella, and the soul of Ysmir, while not able to briing Numidium to god-hood, was able to power it up enough to face stop the aldmeri dominion.
