While the above explanations are good and true I'll add my $.02 in basic words. Toggle turns cause the body to swing out from under the canopy (as related to where the wing loading should be for normal flight). The second thing that happens is that since the wing isn't fully loaded it can't be fully controlled, and thus if you've done the maneuver too low you can't flare because there isn't enough air in the canopy. --- When you do front riser turns the wing stays loaded (for the most part—I have to add this little waiver since it is possible to do riser turns that cause a short duration of de-loading and weightlessness). This means the canopy has a full amount of air in it and keeps its shape and potential energy and performance. Regardless, it's still possible to do front riser turns too low. One last tip for riser turns: be sure to move the toggles slightly down on the steering lines a little (creating more distance between canopy tail and toggles) so that when you pull on the risers you’re not also pulling on the tail. This alleviates the buffeting. HOWEVER, doing this does mean that your flare point is LOWER. One must pull the toggles lower down in order to cause the same flare!!! Be sure to practice flaring at altitude and normal landings after adjusting the toggles!!!
