My 1990 CRX had DFCO over about 2500 RPM. Heck, in the early 1970s some of the earliest fuel-injected cars (aircooled VWs using analog electronics to control the injectors!) had DFCO. So it is entirely possible that a 1989 Toyota had it.
An automatic transmission can keep spinning an engine on overrun. Some seem to decouple from the engine (or come close to it) when coasting, but others still keep the revs up.
I am not familiar enough with Toyota drivetrains to say for certain on either count.
