You are correct. Making an ext2 filesystem on the floppy is indeed broken. Attempting to read/write from the resulting filesystem results in the following type errors:
Sep 1 13:18:23 dad kernel: EXT2-fs error (device fd(2,0)): ext2_check_page: bad entry in directory #11: unaligned directory entry - offset=7168, inode=1431634935, rec_len=50, name_len=0 Sep 1 13:20:20 dad kernel: EXT2-fs error (device fd(2,0)): ext2_check_page: bad entry in directory #11: rec_len is smaller than minimal - offset=7168, inode=0, rec_len=0, name_len=0 Sep 1 13:22:29 dad kernel: EXT2-fs warning: mounting fs with errors, running e2fsck is recommended Sep 1 13:23:09 dad kernel: EXT2-fs error (device fd(2,0)): ext2_check_page: bad entry in directory #11: directory entry across blocks - offset=7168, inode=861697588, rec_len=12592, name_len=119 Sep 1 13:24:38 dad kernel: EXT2-fs error (device fd(2,0)): ext2_check_page: bad entry in directory #11: rec_len is smaller than minimal - offset=7168, inode=0, rec_len=0, name_len=0
Putting a text file on the floppy shows 512 byte chunks of the file being moved around depending on how many times the file is read/written.
