That would require going back and splitting the textframe and its inline containers and putting the continuations in the right places, recalculating the metrics for the modified frames, and also undoing float placement if any. It's a lot simpler just to reflow the line again. It's not a full line reflow because we don't do horizontal and vertical alignment etc, and it only happens when a multi-frame word crosses the line end boundary after the first frame, so I don't think it'll be a performance issue.
