It's neither a bug nor undocumented.

"info ls" would have told you the following:

     The permissions listed are similar to symbolic mode
     specifications
     (*note Symbolic Modes::.).  But `ls' combines multiple bits into
     the third character of each set of permissions as follows:
    `s'
          If the setuid or setgid bit and the corresponding executable
          bit are both set.

    `S'
          If the setuid or setgid bit is set but the corresponding
          executable bit is not set.

    `t'
          If the sticky bit and the other-executable bit are both set.

    `T'
          If the sticky bit is set but the other-executable bit is not
          set.

    `x'
          If the executable bit is set and none of the above apply.

    `-'
          Otherwise.
