As I wrote in the sibling comment to yours, it really could go either way. A confluence, a place where you find a lot of information like an intranet shared drive, is a reasonable interpretation without the original quote in place. But so is Confluence the application as an example of a confluence which also exists on an intranet, and the writer misunderstood and (being a writer) used their familiarity with English to infer more than was said.

We don't need AI for either interpretation, just familiarity with English.
