How does it differ from "Broad Match"?
The name is misleading, "Broad (session-based)" has actually nothing to do with "Broad Match". Here is an example of how the same keyword can trigger different searches based on the match type.
Broad (session-based) is based on the assumption that Google found a relation to the topic of nail polish and thus "aids" the campaign in having keywords show up for related topics. This can be a gold mine or a complete pit fall. That's why it is so important to watch this match type closely.
Broad Match means that either of the words "strong" and "nail" have to be part of the search but not necessarily both words. Obviously, a good campaign manager should work with negative keywords to avoid showing up for things like "strong alcohol". However, the table above shows the difference between the two match types very clearly.
