Correct. This is a known bug in the RTWMC, and can and has been overruled if you contact SQ directly. Ie. on my RTW last year I ticketed OSL-LYR direct (1255mi), even though there is a stopover in TOS (1292 actual flight miles). The key, though, is that it must be the
same flight number, so you can't use this all that often.
