I just noticed that you're using the same file for input and output! Of course it will remove all its content because the redirection is performed first.
You should use a temporary file like this:

lzdiff
XZDIFF(1) XZ Utils XZDIFF(1)NAME
xzcmp, xzdiff, lzcmp, lzdiff - compare compressed files
SYNOPSIS
xzcmp [cmp_options] file1 [file2]
xzdiff [diff_options] file1 [file2]
lzcmp [cmp_options] file1 [file2]
lzdiff [diff_options] file1 [file2]
DESCRIPTION
xzcmp and xzdiff invoke cmp(1) or diff(1) on files compressed with xz(1), lzma(1), gzip(1), bzip2(1), or lzop(1). All options specified
are passed directly to cmp(1) or diff(1). If only one file is specified, then the files compared are file1 (which must have a suffix of a
supported compression format) and file1 from which the compression format suffix has been stripped. If two files are specified, then they
are uncompressed if necessary and fed to cmp(1) or diff(1). The exit status from cmp(1) or diff(1) is preserved.
The names lzcmp and lzdiff are provided for backward compatibility with LZMA Utils.
SEE ALSO cmp(1), diff(1), xz(1), gzip(1), bzip2(1), lzop(1), zdiff(1)BUGS
Messages from the cmp(1) or diff(1) programs refer to temporary filenames instead of those specified.
