That sounds like rubbish to me. If it worked like that, chrooting
servers would be virtually useless. 

Which OS is the ISP using? Tell him to do "man 2 chroot" and read

|        chroot - change root directory
|        #include <unistd.h>
|        int chroot(const char *path);
|        chroot()  changes  the  root  directory  to that specified
|        in path.  This directory will be used for pathnames
|        beginning with /.  The root directory is inherited by all
|        children of the current process. [...]



BOFH excuse #282:

High altitude condensation from U.S.A.F prototype aircraft has
contaminated the primary subnet mask. Turn off your computer for 9
days to avoid damaging it.
