Allow reports to be saved so the criteria can be edited before invoking the query

The CiviCRM report code has this line

// lets always do a force if reset is found in the url.
if (!empty($_REQUEST['reset']))

There is no explanation & the comment implies it was a lighthearted decision. The implication is that slow reports need to render before changes can be made - such as a criteria tweak or printing as a pdf or exporting.

Dgg - assigning to you to see if you know why this might have been done. I'm guessing maybe something to do with assuming people who add reports in the navigation menu would want to see the results rendered (sometimes true)
