Absolute Zero for Black hole not reachable through Singularity

The connection between Absolute Zero and Drifting Singularity doesn’t work by going through Singularity.
I could only find one post about this that that was back in jul’ 2020, back when it had a two point node. Now it has 1 point which FURTHER makes it seem like you are intended to be able to go through Singularity. If you are indeed not intended to go from that side there needs to be a better indicator like an arrow or red line or something. (in the old post, someone said they would fix the clarification and clearly that didn’t happen in the span of 4 years).
Also I see no reason why it should be intended, i don’t think there is anything “broken or op” about being able to chill.
