Well, they were trying to show the typical Jakobs bogie of the french TGV (cf. the orange color of the original TGV south-east until 1989). Correctly, the power car M1 and the first passenger car R1 with the aerodynamic connection to the higher roof of the power car are separated classically with separate bogies. The following passenger cars (R1 connecting to R2, R3, R4, R5, R6, and R7 connecting to R8, the last passenger car) are all linked with a Jakobs bogie in between. Because there are only 2 passenger cars in this set, the second car has to end with a standard 2-axle-car after only one Jakobs bogie between the first and the second. This ending could correspond to the Eurostar version, but this has never existed in this early orange colour. In turn, you could attach another power car (M2) to finish the train.
