That's typical of all Toyota/Lexus 6-speed automatics, be they FWD transaxles or RWD transmissions. And the 8-speed automatics (IS F, LS) also have 6th speed direct and overdrives on 7th and 8th.
I'm pretty sure the main reason is for better EPA cycle highway fuel economy numbers, with quieter, more relaxed freeway cruising as a side bonus.
