Dessamator said: When one uses S:C they automatically pick up the browser, the OS, and possibly even the wikia in question, which greatly reduces the questions they need to ask, and make it easier to triage the bug.

This is correct. Not only does multiple reports help triage the bug, but it also helps understand how many users are affected by it. This adds to the general scope of the issue.
