That’s expected. :-) I’ve clarified this in 0767f6a:
@@ -6302,7 +6302,12 @@ is interpreted as a partition label name; when it is
@code{uuid},
@code{device} is interpreted as a partition unique identifier (UUID).
UUIDs may be converted from their string representation (as shown by the
address@hidden -l} command) using the @code{uuid} form, like this:
address@hidden -l} command) using the @code{uuid} address@hidden
address@hidden form expects 16-byte UUIDs as defined in
address@hidden://tools.ietf.org/html/rfc4122, address@hidden This is the

When we implement FAT UUIDs, we’ll either adjust the ‘uuid’ form or
introduce a separate ‘fat-uuid’ form.
