It's sort of the opposite of what I'd expect. I'd expect mapping[stream_index] = vorbis_index, but it's actually mapping[vorbis_index] = stream_index.
And so I guess that means that the interleaved audio samples you pass into opus_multistream_encode_float() should always be in Vorbis order, and mapping[] just tells the encoder how to package them in the streams?
