Page break module prevents indexing

Does this also apply to Google?

Looking at gsitemap the only page indexed seems to be the first. Is this something to do with the ?page=0%2C1 in the URL (something like _p2 would certainly look more inviting to both humans and search engines) and is it avoidable?

While the module is a great idea if all pages after the first are effectively invisible to Google etc that would be a major drawback.

That's theme_pager()'s result, from drupal 4.7.x core.
