From: Nika Layzell <nika@thelayzells.com>

Uses the FILTER flag on patch flavours in git-add--interactive to determine if the initial index refresh call is required. It is not required for the reset patch modes, which use the 'index-only' filter, as they do not interact with the worktree, so do not need up-to-date stat information.

The refresh call can be quite expensive, especially on larger checkouts or with a freshly created index file.
