By jlyman:

Right, I was aware of that. When using checkboxes, it makes most sense to
be implicating an OR in most use cases. However, $selected_terms there is
just being used (as far as I could tell) to indicate to the list walkers
what was already selected, so that it could properly check/select/change
the URL it the taxonomy term was part of the query. Exploding on only a +
sign would cause that to fail for a checkbox list of ORed items. Is
$this->selected_terms used for anything other than showing to the user what
was part of the request?
