It's not needed and in fact often not used. Rather than say "only a drill," perhaps better to say one way of many to hook up a ski, and one that requires a certain amount of time and line and, in the context of racing in many contexts is slow. It's main use in developing racers, for instance, is as a drill and not as a default movement pattern. For instance, given the emphasis given this type of transition on here, it might seem surprising to see that, say, at a week's worth of race camp it might never come up and the drill might never be done. That's not speaking against it, and it can be a good way to introduce skiers to using the shape of the ski to turn.
Here's a more-common variant,
And in fact as a drill outside edge to outside edge I would say is a more common drill at race camps as well. One ski skiing which admittedly is a more-advanced drill in the teaching context that can lead to many bad habits is again a much more common drill at race camps, and by definition does not allow for inside ski tipping to initiate moving off of the new outside ski's LTE, because there is no new inside ski (except in terms of available rotary inputs from that leg which are of course still there).
