Although the Houthis Armed Forces and Iran are closely connected, they are ultimately not one and the same. No matter how deep their entanglement, they can't be completely aligned, and each has to consider its own interests.
Gao Yang was just puzzled as to why Abdullah and Saeed would argue in front of him. Here, the Houthis Armed Forces and Iran are like brothers, even if they are breaking bones, they are still connected by tendons. It's hard to imagine them arguing incessantly in front of him, an outsider representing Russian interests.
However, after observing for a moment, Gao Yang understood. It wasn't that Abdullah and Saeed were putting on a show for him, nor were they harboring any complex thoughts. It was merely that the Saudi airstrike had left everyone a bit panicked, and they were hastily trying to come up with a plan to respond, yet couldn't agree on one.
