The NOTICE OF MISTAKE clears up a mistaken presumption(s) by the court & disassociates the word 'YOU' & the name in question from the MAN in front of them, thereby deflecting surety & making it very clear that you cannot be acting as trustee for that name/account/charge/instrument.
It keeps you in honour and removes any presumptions that the court may have about who 'YOU' are (or in this case are not).
It allows the court to get on with its own business of administering an account that they created and mistakenly presumed you to be acting as trustee/surety for.
