As is often the case with new trainsets running in East Asia and South East Asia, most of them omit overhead cabinets. The new trainsets on the article also omit those cabinets.
Even in Japan, where overhead cabinets on trains are still common, less and less passengers put their own baggages there. That's probably because they are easily to forget them when alighting from the trains.
On the other hand, railway companies in Japan try to enlighten people to put baggages on the cabinets.
It's interesting to see how railway companies deal with the trend.
