The patch v2 has always had the comment and intent

+	# To make sure we are actually testing both the same-page and
+	# compression paths, we first pad with zeros but then fill
+	# with a compressible series of alternatiting 0x00 and 0xFF.
+	# This should assure we stress the compression path and can

I believe this tests both paths, and in a more rigorous manner than the
extant test.
