Well, actually it will, smarty pants. Because the negative 'g' limit is much lower than the positive 'g' limit. So, when approaching the assigned altitude in a high performance jet, it is quicker to roll inverted and pull hard to the level off attitude, then roll erect than it is to thottle back and pitch to the level attitude - or even to push to the negative 'g' limit to stop the climb approaching the assigned altitude.
We were taught this on the Gnat. On early trips we throttled back and began to level off at around 1500 ft to the assigned altitude; on later trips we waited until a few hundred feet to go, rolled inverted, pulled to 3 or 4 g, levelled off and rolled erect....
The braver guys did the same thing at low level to avoid ballooning over hills
