No, the plug is tightened and expanded well before the stem is fitted. Since the stem must be loosened for the headset to be adjusted you can't count on it for support against plug pressure.

In some cases I've seed steerers distorted enough that the stem even when tight rocks slightly and creaks when sprinting and climbing.
