Looks to be a feature in sys/kern/vfs_mountroot.c:
997 parse_mountroot_options(struct mntarg *ma, const char *options)
:
1021 if( strcmp(name, "rw") == 0 ||
1022 strcmp(name, "noro") == 0) {
1023 /*
1024 * The first time we mount the root file system,
1025 * we need to mount 'ro', so We need to ignore
1026 * 'rw' and 'noro' mount options.
1027 */
1028 continue;
1029 }
