already decades ago germany and i don't know which other countries started charging more for these flexible tickets and you could get cheaper tickets if you booked a particular train in advance. i suppose the advantage is that by committing to a particular train it is easier to predict which trains will be full, and potentially even do something about it like adding a car to fit more passengers. as far as i know, this only applies to long distance trains and not to regional trains. israel is a small country so all trains are more comparable to regional trains. selling such a ticket right before getting on the train of course doesn't make any sense.
