This code makes my brain hurt now as well (how on earth did we ever decide that using plain ints in different ranges to represent different kinds of ID was a good idea?) but I agree with you on this, the thing returned by *connections.begin() is an instrument ID not a counter or index. So it could be, for example, 10000 which represents the first synth instrument (synth instruments have IDs starting from 10000). Subtracting one would give you 9999, which would theoretically mean the 8000th MIDI instrument (because MIDI instruments occupy the 2000-10000 range) which is not at all a meaningful thing here. There's obviously some interesting mystery being hinted at here, but I don't quite see what it is either.
