I am not aware of it having an effect on lofts. In fact I don't think it appears in the loft blueprints anywhere.
Its used to make child objects sit on the ground. For example if you have a blueprint that consists of houses on a residential block, you might make each house a child component of the block blueprint. Normally those houses would all be at the same elevation so if you were to put the block on sloping ground, some houses would float in the air. But when you check "Track terrain in editor", the houses will drop to ground level and properly sit on the sloping terrain.
Use this feature for example, a row of cars in a parking lot, or a bunch of corn plants in a field.
