(2) Notwithstanding the provisions of subsection (1)(a) of this section, an agent may, even in the absence of a specific grant of authority, make transfers of property to any trust that benefits the principal alone and does not have dispositive provisions that are different from those that would have governed the property had it not been transferred into such trust.

(3) Notwithstanding the provisions of subsection (1)(b) of this section, an agent may, even in the absence of a specific grant of authority, make any transfer of resources not prohibited under chapter 74.09 RCW when the transfer is for the purpose of qualifying the principal for medical assistance or the limited casualty program for the medically needy.
