You just can't "retroactively" edit the schematics by placing new components to the PCB design + editing traces, and importing the implied changes back into the schematic editor.

You can do some things on the layout which get back-annotated to the schematic but nothing like "let's add some components and define their connections right on the board". Even if it was possible, I probably wouldn't use it. Schematic should to be defined/captured on the schematic editor or your error (aka unusable boards) rate is going to soar. So in this sense it is quite similar. As for automatic annotations from schematic to the layout - well, I guess one can either get used to an additional step or two or set up a watch script to react to updates to the netlist files.
Hmmm, while this is not a showstopper, it does seem awkward.  My 
workflow now is to load the sch in one monitor, the brd in another, and 
move wires around on the CPLD all the time until I can get the layout to 
work well.  Having to import and such could really slow down CPLD/FPGA work.
