That's impressive if it's actually able to adjust its own thresholds so that I can tell it to modify its behavoir (rather like Interstellar's Tars being told to adjust its humor and honesty parameters). Without using Abacus I have a hunch that it's just telling you its capable of that. LLM's in general know very little about themselves, only what they're told in the system prompt. But system prompt could include tool use that alters its own behavior.
