Smart close vulnerabilities is a feature which compares the results of the latest scan with the previously run scans on the same target. Once the results are compared, if the vulnerabilities identified in the previous scans are not identified in the latest scan, then the vulnerabilities which are not identified in the latest scan will automatically be moved to the 'Resolved' state. You can enable Smart close while importing reports as well. The way it works with report imports is very similar to how it works with scans. Strobes compares the vulnerabilities which are imported from the latest report with the previously imported reports. If any vulnerability is not present in the latest report but if it is present in the previous report, the it will be automatically moved to the 'Resolved' state.
