With both enabled, only the Clock bit gets set (2X mode) and and device has to be set into ISP mode again
to program the P89VRD2 again to set the security bit.

This is true for all the versions I have used so far.

That might be an issue with older bootloaders in this particular device as it sounds familiar. Try the version 7 bootloader.
