Well, you're right. There's another issue if the monsters are expending energy to keep you in the box.

Why don't two monsters have longer attacks?

Per the energy expenditure, two monsters should have the power to have one monster's turn immediately followed by the other's. They choose to instead overlay their attacks. All this is well and good, but the attack duration is exactly the same as if it was an individual.

Under this, the two-monster example shows a flaw: Each monster is only expending half as much energy to maintain the box as they normally would, but they don't seem to use the extra energy for anything. The attacks are the same, just combined. The only way this works is if duos slack off, which seems unlikely with the CORE mercenaries.

...yeah, the battle-box seems weird. Although the size thing does explain why that's used exclusively by Flowey, Asriel, and Sans: bending the rules.
