Not according to the guy in the Fermi lab video posted above. It doesn't appear to be a case of words failing either. Two different people have said they are different phenomena, and the guy mentions in the vido that light slowing through a transparent medium via absorptive/re-emission is a common misconception. He then goes on to give a reasonably layman's explanation of the truth.
