No, if i remember reading correctly..
The maid accidentally smashes a vase that scrapes jesse causing him to bleed excessively. They find out about his hemophilia. Due to his anxiety of not wanting his condition to be known, he asked Law to create / improve Moritat to erase their memories.
I think Law found jesse's condition convenient for him since he really wanted jesse to admit to the virtual reality program.
So.... The maid saw the amount of blood and Law took the blame and told them it was HIS condition??
