It's broader than that and includes 772/773s and occasionally 77Ws. But yes, mostly regional intra-Asia, occasionally Asia-Australia.
I'm about to test this later tonight, trying to put together a complex itin that includes SIN-BNE & return, hopefully in SQ Biz. Not great seats on the 330, but hopefully good enough to get some sleep in on a 9-hour overnight flight.
