Is this also a "push-pull" train?

Usually we call it a "push-pull" train in Japan if a train has at least 2 locomotives ( 1 at the head, another 1 at the end ) here in Japan. But wonder if this below is also called a "push-pull" train or not :-)

A locomotive is located at the middle of a train!
Can never find this in Japan.
Basically I feel it's a bit vague which is a "locomotive", which is a "passenger car " and which is an "electric passenger car" there in Switzerland. For example an electric passenger car has 4 big motors and pulls other 9 passenger cars ( totally 10 passenger cars ). I think it must be an electric locomotive if it's in Japan. But things go different there.
Actually they don't need to replace the locomotive even when they need to do that if locomotives can be located at the middle of a train like that. My point is why we can not find this way in Japan? Maybe because some restrictions for safety or what?

　By the way, you can find a train for cars around 0mins 50 seconds of this clip above. I think that is a car train which takes cars, buses, trucks through the European Alps to the opposite side because in some points there are no tunnels for cars while there is a tunnel for railway. Maybe ancient people might have guessed someday in the future people need to control to exhaust CO2 :-)
