Yep.
It makes sense when you learn that women cannot go to the high level of celestial being without a call from their husbands, so that leads to polygamy.
Many of these baptisms are for un-married or suspected un-married women, so they can be called.
It is better to baptize them, just in case they were not married or not married to a “mormon man”.
So lds do practice active polygamy today.
