Why do you bring up psyching here? It’s an obvious misbid and the point worth discussing is whether S has made use of UI or not, and that depends on their methods and agreements. Unfortunately, we don’t know what these are. Neither do we know what East’s 2♥ means, but, by the look of it, both majors. If that’s the case, I would consider pass the logical call, “Wait and see”.
I didn't bring it up, it was brought up in OP.
And the laws define psyche as "a deliberate and gross misstatement of honour strength and/or of suit length".
So the relevant legal question in this case should be whether the (obvious) misbid may be corrected under Law 25A1 or should be considered a psyche subject to possible restrictions under Law 40B2{a}{v}.
Now, if South suspected a genuine and unintended misbid he should have called the Director rather than making a call. That would have kept the door open for North to change his call under Law 25A1.
By passing South apparently "fielded" the misbid as a psyche.
