The answer from the author (sorry for the ungrammatical translation):
1 "If anyone wants to save the value of FF lockbits it means that he does not know what this is, unfortunately, because it looks that someone wants to delete fusebits and this can not be done if they are set - unless you delete the entire processor - this operation deletes only lickbits
2 and the value of CC? is a value from space
I propose to use the tab in the program LockBity MkAvrCalculator - where you can clearly choose what we want to set security
And typing manually in the form of HEX lockbit?s - this must first be familiar with and know well the same AVRDUDE to know what's going on
generally the case that AVRDUDE never sees the value of FF but 3F, since only the two oldest bits are always 0 for him
So it seems that everything is in perfect order
and how someone wants to save himself some value and then let it check whether the security is enabled - after all it is easy to check."
