It's the second step that counts: Arylation of Pd by Au takes place through transition states and intermediates featuring strong Au⋅⋅⋅Pd metallophilicinteractions (see picture). However, the aryl transfer from [AuArL] to [PdArClL2] is thermodynamically disfavored and will not occur unless an irreversible ArAr coupling from [PdAr2L2] follows.
