Come on - give Kamala a break, Venn diagrams are hilarious to everybody! That's what all the laughing and exaggerated hand waving is all about.
Kamala has the mind of a 12 year old. Everything that is everyday normal to us, is a 'new' and 'fascinating' wonder to her. Especially satellites and space. She speaks as if she just 'discovered' both earlier this year. On the DMZ she said to the soldiers there, "Do you know...do you know how big space is? It is very very very big. Bigger than anything! And, and, and, the Earth ... the Earth is a planet floating in space! Can you believe that!?" while she was sucking on her juice box. Then she got distracted by a bird and forgot what she was talking about.
