Yes.

I've found a couple of websites saying that before using material with
a CC licence --- any licence --- verify with each and every copyright
owner that you can use it,  prior to using it.  If you can't find the
copyright owner, then treat it as an orphaned ARR work.

The primary reason for doing so, is to verify that the material really
was issued under the licence you have.  The secondary reason for doing
so, is to verify that your understanding,and the copyright owner's
understanding of the CC are more or less congruent.

Note that this primary problem (lack of certainty as to copyright ownership) applies to all CC licenses and, in general, all copyright/IP licensing.
