The grid code first retrieves the records and then calls the selectable callback (which it must do, as the record ids are passed to the callback), so if the callback makes any modifications to the records, the resulting grid will *not* contain up-to-date data unless the grid is called again (hence the redirect). I think the idea is to ensure it works in all cases, though I agree it could be made more efficient in some cases. For now, a workaround is to check for request.post_vars.records, and if present, run whatever code you need to, and then delete request.post_vars.records and request.post_vars.formname before creating the grid (this will prevent the form from being accepted and therefore skip the redirect). You could abstract this into a wrapper around the grid.
