In this NASA Goddard YouTube video titled "One Year on Earth – Seen From 1 Million Miles", I've gotten stuck on the line
In this view, EPIC sees the Sun rise in the west, and the Sun set in the east, at least 13 times a day.
edit: Listening carefully, it's "...see the sunrise... and the sunset..." and not "...see the Sun rise... and the Sun set...", so my transcription is not correct. I'll leave it, along with this note, because the distinction is important. I only caught it after reading the nice, concise answer by @Leorex through carefully.
DSCOVR is in a Lissajous orbit about the Sun-Earth L1 Lagrange point between the Earth and the Sun, and the EPIC camera points towards the earth which remains nearly 100% sunlit.
A given point on earth sees about one sunrise and one sunset per day, and the Lissajous orbit gently rocks back and forth slightly with roughly a six month period.
I don't understand what it is that is happening at least thirteen times a day. Can someone help me understand this?

you can see the "chunk of missing earth". But OK I know what you mean. Do you think you can post this as an answer? $\endgroup$
