It's a bit messy.  You want the following-siblings of the foo that
have a following-sibling which is the first bar after the foo.  So
set a variable $bar to following-sibling::bar[1], and use

  following-sibling::*[generate-id(following-sibling::bar[1]) = generate-id($bar)]

In this case generate-id works better than counting the union because some
of the elements may not have a following bar element.

For more complicated examples you might want to use "Muenchian grouping"
(see Google).
