Except that is not all we're talking about. There are at least four separate things being done during this "movement", including health bar adjustments, removing effects, adding effects and the 'rez' animation itself.
Ignoring those other four things is where you continually go wrong.
Oddly enough, that portal movement does not involve health bar adjustments, removing effects, adding effects and presenting a 'rez' animation. Who'd have thought otherwise?Diamond Weapon example clearly contradicts this.
