Imagine if there was a portal on your front lawn that allowed you instant access to downtown London. How much more frequently would you travel to London if it took you literally no time at all? All of those trips are induced demand--that is, it is extra demand that is induced by the ease of the trip. Shifting demand from one route to another is, by definition, not induced demand, since it already existed!
Every time you decide to delay a trip during rush-hour, because of rush-hour - that is an example of what you are describing.
As an example, in Bellevue, Washington - the evening rush hour starts (and is really bad) at 3pm - there are that many people leaving work progressively earlier that there is still a rush hour of people leaving work early to avoid the big rush-hour.
