Here's the thing... Direct Injection leads to dirtier oil, polluted with sot. With Honda's NA motors, I'd go no longer than 5K miles between oil changes.
Now, add Forced Induction to the formula. The oil is going to sot up even faster. Oil changes on a turbo charged motor should be done every 3-4K miles.
Not changing the oil frequently enough will lead to dirty intake ports/valve backs and dirty/stained/sludge caked engine internals. This type of build up is wearing on the moving parts and therefore, shortening the engine life as well as lowering the fuel economy.
To answer the OPs question...
Perhaps the maintenance minder wasn't reset at the last oil change, OR the computer detects harder use on the drivetrain. It can calculate and make adjustments to the maintenance scheduling.
