I'm not familiar with how in depth the theory of Frisk being stuck in the barrier is, but I wanted to add potential support to that: Alphys and the murals in the Waterfall may have been missing a vital piece of information.

In Frisks case, the assumption everybody had was centered around needing two types of souls to cross the barrier. Instead, who the HOST is might be a major factor as monster souls may disappear just as quickly after being absorbed. It seems like the whole underworld generalized to what was needed to cross the barrier without thinking through HOW the process needed to occur.

The only instance where souls were joined supposedly (documented anyways) was when Asriel absorbed the soul of Chara - in that case, there were no problems with a human soul disappearing since they're apparently extremely persistent.

Given that Asgore's soul was taken by Frisk in the end, it may very well be that it was absorbed just to shatter "moments" after Frisk started crossing the barrier, explaining also why their cellphone could still be reached as they couldn't have made it very far in.
