That space is where the $BOOT file is placed which contains the bootstrap code and the BIOS Paramether Block which includes the NTFS signature and describes various filesystem information needed to locate the superblock, etc. Unlike mkfs.xfs which warns since at least 2002 and requires the -f option to override Sun disklabels, at the moment mkfs.ntfs will indeed destroy them. Thank you for the bug report and let's hope the next generation of Sun hardwares won't scatter the firmware too into random places inside a partition encoded by a fictitious size of disk cylinder.
