Slowing down to a safe speed to maintain visual reference with the ground whilst negotiating the weather doesn't cause a loss of lift and the helicopter doesn't fall out of the sky. The only hovering you should be doing is whilst IGE, in the process of landing. I dare say that the helicopter in this instance had the performance available to do that.
