"EXCEPT TO PAY FOR LEGAL COSTS AND FEES"
https://ia804708.us.archive.org/26/items/gov.uscourts.nysd.5...
Selling something where the proceeds are intended to be used in a later transaction to pay legal costs and fees would still require pre-clearance.
Otherwise, it would be a vacuous restriction, as he could literally conduct any transaction (at least, where money flowed to him; it would be harder but not impossible to justify asset purchases) on the justification that he would eventually be using the proceeds to pay legal costs and fees.
But, if you violate the terms of your bail, you can end up back in custody.
I agree it's suspicious though! I hope it's thoroughly investigated and his bail revoked if he is in violation.
