In my experience this is only partly true.  Stand alone apps seem to run fine.  However, things that run in the system tray are problematic.  I've had no problem if I run 4.1 in a second X session where both 3.5.9 and 4.1 are running for the same user.  If I run only 4.1, there are problems.

Knetload and guidance-power-manager launch (I can see the processes), but don't appear in the 4.1 tray
smb4k and amarok launch to a full window but won't go to the tray.

Also, I can't install any of the plasmoids on kde-look.org, even those stated to be for 4.1 and not 4.0.x, so I still can't get to the full 3.5.9 functionality.  That said, 4.1 is actually usable, unlike 4.0.
