No, "this document" only means this LICENSE file, but clause #2 also requires reproducing
the COPYRIGHT file. And individual files within the source tree have their own particular
copyright statements, which clause #1 requires they reproduce as well.

My reading of the BSD-3 Clause indicates that there is only a single copyright owner
and single copyright statement for the entire source tree, but that is not the case here.
