I'm a private IFR pilot. This clearance always confuses me: I am on a
STAR with a published altitude restriction of 6000 feet at fix. ATC
cleared me to descend and cross fix at 6000. 10 miles from the fix,
ATC tells me to "descend to 4000." Do i still have to cross the fix at
6000?

dont ask us. ask the ATC guy. he may have overlooked something.
they are human.
