How do controllers coordinate clearances through sectors?

I used to handle that by saying to the new controller "BuzzBomb 234X, 7000
feet, on a vector." A previous controller can't issue an instruction that
has any effect in a subsequent sector, to the best of my knowledge,

But that clearly isn't the case. My original clearance was to go out
to a VOR, then follow one airway, turn 90 degrees go up another airway
etc. A previous controller changed my clearance to be direct (a much
different route), which had great affect on not only the subsequent
controller but about 3 controllers after that as well.
