Rathians are adapted for attacking on land while Rathalos is more adapted for attacking while flying.As you saw in the size video Seruregiousu attacked the Rathian from the air while she can not even defend herself meaning he his advantage over the Rathian (and in case she shoots fire balls at him he will evade).And when the air based Rathalos came and attacked it,you could imagine imagine what trouble it would be for Seru if a Rathalos is attcking it from the air and Rathian is shooting fire at him from land.Fleeing is a more safe option.
