Quoting mdoc(7):

	The -width and -offset arguments accept
	macro names as described for Bd -offset,
	scaling widths as described in roff(7),
	or use the length of the given string.

Is your -width a macro name (such as Ds) as descibed for -offset? No.
Is it a scalinbg width as described in roff(7)? No.
Apparently, mandoc uses the length of the given string then.
AFAICT, that's what you told it to do.
