How exactly did the barrier open in the True Pacifist Ending?

As we know, the barrier can only be shattered with seven human souls. At the end of Pacifist, Asgore has collected 6. You are still alive, and Chara is presumably soulless, seeing as they "sold their soul a long time ago," so unless I'm missing some mechanic on the barrier, it should be impossible for the barrier to break.

The most common retort is that with the power of every monsters' SOULs, the barrier was shattered, but I don't see why this would be the case. Asriel is a boss monster just as Asgore is. He clearly survived the barrier shattering, so there's no disadvantage to using your own SOUL to shatter the barrier; why would Asgore not do the same if this was really how the barrier was shattered?

And, remember, between the start and end of the battle, Asriel doesn't actually gain any more SOULs. When you start the Asriel battle, Asriel has the 6 human souls and the monsters' SOULs, and that's it. The barrier theoretically shouldn't have shattered.

Again, forgive me if I have messed up somewhere along the way, but I'm in a pickle as to how the barrier would shatter in True Pacifist.
