一个语法疑问

What is mirrored in this picture above is that......
上面一个主语从句+表语从句.我对that要写的内容有点疑问
正常情况下是写一句话，这个我觉的没问题.
我问的就是that后面能写两句话呢？并且不是用连词直接连接的那种（如and,because),而是用句号连接.
我举个例子
What is mirrored in this picture above is that three sons and one daugther of an old man keep their own goals.They kick their father as a ball.
到底能不能这样用呢?我知道把后面改成状语成分用起来最好（kicking their father as a ball）,我就是想问下语法上能不能这样用？
请知道的朋友解答下，谢谢！

that 后面可以跟两个句子，但是这个句子要是按照那么改就有点牵强
three sons and a daughter of an old man keep their goal. They kick their father as a ball这一句应该是对前一句的意思上的补充
