Usually I think that second woman is not there; maybe in this drawing she is placed there to explain why the young woman in the Boring figure is turned away – she’s talking to this other person.
Btw, that tv occurrence was in a miniseries called Defending Jacob
I didn’t recognize the classic illusion figure (on the right) until I read Mitch4’s comment, my first thought was that it might be a reference to the Finck panel in last week’s Sunday Funnies:
The Happy Birthday day one reminded me of the “Ship of Theseus” paradox. I get the joke, but the humor was lost on me because my mind went to thinking about what defines a person.
All of us have had almost every cell replaced.
Yes, I think the second figure was added for the comic. I don’t recall seeing it that way before.
I learned how to draw the young lady / old lady illusion, but somehow when I draw it, it also looks like a dog.
“I get the joke, but the humor was lost on me because my mind went to thinking about what defines a person. ”
My issue was confusion as to why, if they were insistent on separating him by his individual components, they would view him as an individual enough to have a birthday. Unless all his components are from people with the same birthday which is an impossible coincidence. Unless for some reason that sought out people with the same birthday.

Comics I Don't Understand 
That’s two strips lately using the classic “old lady or mostly turned away young lady” optical illusion.
I missed the other occurrence dvandom refers to. However, it came up in a tv scene just the other day, where for the first time I learned that it has a name: the Boring ambiguous illusion. See https://io9.gizmodo.com/the-worlds-most-famous-and-ambiguous-illusion-1646895274 .
