That’s not mentioned in the summary. After inflation the event horizon would not exist.

This identification happens in equations 31-34 on page 7f subsection "Cosmic Acceleration" in https://arxiv.org/abs/2505.23877
The justification looks super sketchy and hand-wavy to me, though, which I summarized as "somehow (?)".
"After inflation the event horizon would not exist."
Apparent cosmological constant viewed from the bouncing inside induces a cosmological horizon, which they identify with the black hole horizon viewed from the outside. Super elegant idea, but I don't buy that this is supposed to be true.
