The manual explains it:

    The right-hand Bit-depth figure is the standard definition of
    bit-depth i.e. bits less significant than the given number are fixed
    at zero.  The left-hand figure is the number of most significant
    bits that are fixed at zero (or one for negative numbers) subtracted
    from the right-hand figure (the number subtracted is directly
    related to Pk lev dB).

The 16/16 figure reported simply means that the audio data could be
represented in 16 bits.  Since it came from a 16-bit source, this should
be no surprise.
