You incline your body into the turn--it will feel like falling--which will both tip your skis and move you inside the path of your skis, where you will be in balance later, when your skis engage and carve back beneath you.
This is the problem for most skiers, not the solution.
When skiing you should not need to create a feeling that you are falling. It may happen that you sense you are losing balance, but don't purposely push yourself out of balance. Done right even upside down, high C positions don't or shouldn't feel like you are falling. The idea that you need to put yourself in a situation where you feel like you are falling to move inside the turn, is just part of the convoluted traditional approach. It is a necessary ramification to get around a missing connecting blocks for a faulty methodology.
This is just an excuse for poor teaching. These instructors will even go as far as telling you to push your "center of mass" downhill. These approaches are needed and mandatory in their system, because their system is flawed. Their systems omits numerous key ingredients that are building blocks for good skiing. In fact, they never address tipping or flexing. If they do they usually teach it giving the wrong timing in the arc for the skier. This has long term negative consequences that are very difficult to unlearn. Which is worst than not teaching it at all. Why go down that road filled with traps and missteps?
