Actually it is not exactly the same as wrapping a div around p.speaker and p.verse:

p.speaker+p.verse selects the first p.verse following any p.speaker, so the page-break-before:avoid; prevents a break between p.speaker and p.verse, and page-break-inside:avoid; prevents a break inside the p.verse immediately following the p.speaker, but unlike with the wrapper div it is still possible to break inside the p.speaker.

So you would also need to add

p.speaker {
  page-break-inside: avoid;
}

but it is not possible to select only the p.speaker preceding a p.verse so this would have to apply to all p.speaker.
