All explained in TFM.. ksh(1)

       The following is a list of things that are affected by the state of the
       posix option:
         o    \"  inside  double  quoted  `..` command substitutions: in posix
              mode, the \" is interpreted when the command is interpreted;  in
              non-posix  mode,  the  backslash  is stripped before the command
              substitution is interpreted.  For example, echo "`echo  \"hi\"`"
              produces `"hi"' in posix mode, `hi' in non-posix mode.  To avoid
              problems, use the $(...)  form of command substitution.

So it seems sh does the non-posix mode, and ksh by default does the posix
mode.. Sure enough set +o posix fixed things for me..
