I don't know, but without those lines the effect is that each voice gets
to be on its own staff, only the first of which is in drum mode. I guess
that \\ creates the needed Voice contexts if they don't already exist,
but uses the default Voice rather than DrumVoice, which is then
'rejected' by the DrumStaff, pushing the voices out into separate
staves.

It sort of makes sense if I think about it as a programmer, but as a
user it's pretty annoying behaviour, especially as the first time I came
to do it it took a few hours of flicking between pages in the manual to
work out the appropriate incantation, and to find the skip-of-length
thing.

Isn't the missing tie just the usual "ties can't cross voices" problem?
I tend to work around that by the trick of 'hoisting' one end of the tie
into the other voice, replacing it with a space in its original voice.
So, in your example

the relevant lines become

    sn16 sn8 sn16 sn8 sn8:32~ sn8 sn8
    <<
      { s4 | \repeat unfold 16 hh16 }
      \\
      { sn4:32 ~ | sn4 sn8 sn16 sn16 sn4 r4  }
