Don't think of seeing the Steering Wheel in the Assembly environment as being a "synchronous" application. While the Steering Wheel in Part/SheetMetal is used for synchronous face editing (push/pull/rotate/copying, etc), in the Assembly environment, think of it as another tool to gain effeciencies. Whether your models are completely Synchronous, completely Ordered, or Integrated (combination of the two), the Steering Wheel can be used in Assembly to do a number of things. The applications I think of right away are:
1) Use the SW to relocate/change part orientation/position within the assembly. Select the part/subassembly and use the SW to drag/rotate the part to a new position.
2) Use the SW to make additional instances or copy the part. Select the part/subassembly and by either selecting the "Copy" option in the Quickbar or holding down Ctrl key, you can duplicate your part without going back to Part Library.
3) Use the SW to apply intelligent assembly constraints. Select the part/subassembly and relocate the origin of the SW to a reference point on the selected object. Use the axes of the SW to move the select part/sub to another keypoint relative to another part/sub. If you have the appropriate options turned on in the Options menu (located in Quickbar), Solid Edge will recognize the relative position of geometry between your components (mates, hole alignments, etc) and automatically apply those constraints to your model.
All good stuff (regardless of your chosen modeling approach).
