As you noted, there's only the one instance in the statute where reasons are required. If the committee feels that determinations are being made in an inappropriate way, obviously they will be able in their reports to make note of that and to flag the fact that in their view there is a problem that is occurring.
The various clauses that you referenced are different decision points. The first one talks about the review of national security matters at a high level, and then the other ones talk about access to specific information.
In terms of answering your question, what I'd say is that the bottom line is that if the committee is not satisfied with what they're seeing, they're perfectly at liberty to note that in their report.
