It does! I counted it as decluttering when mine moved out.Mary, we have been using the same gift bags for many years, a few needed to be tossed this year.
DH has moved out to his own house 3 hours away from ours. I now have an empty sunroom and another empty bedroom. He took most of his things with him and will take more when he comes back to visit. I think this would count as decluttering.
