I don’t think the powers are really that analogous in method, but more importantly, they do share some potential uses… I think you’re right, it’s kind of interesting that Canary and Heartbreaker were introduced in adjacent chapters. “Here are two people who committed sexual assault with mindbending powers, compare and contrast.”
Canary could absolutely do something similar to Heartbreaker if she really wanted to (though perhaps with more effort to keep it up), and if that did occur to the prosecutor, the example of Heartbreaker would go a long way to convince the judge and jury that her power is dangerous to the masses. So yeah, they probably did bring it up.
