A "provocation". White could have simply waited (but then Black would finally come back to the ...b5-b4 idea). [44.Ld1

44...h5!?
Black tries to counterattack on the same side where White has an attacking setup. Such a double-edged approach works when the opponent's pieces are not mobilized enough. Does the fact that White's queen is just a tempo off the main battlefield mean "insufficient mobilization"? The analysis shows that it apparently does but Black fails to prove it over the board!
