Yes,
you either have not read or not understood
the man page for amrestore.

An amanda tape is a sequence of "tape files", all but the
first and last containing the resulting dump of a single
disklist entry (DLE).

Each and every tape file begins with a 32KB header (note the
"h" in header) identifying that tape file.  The "-h" option
of amrestore outputs only the headers, not the dumps.
