I don’t know if you’re joking, but I don’t see anything in the linked tweet which suggests that is the case

Watch the video. It's from then-Gemini-lead Jeff Dean and the video shows off an animated pelican riding a bicycle, a frog on a penny-farthing, a giraffe driving a tiny car, an ostrich on roller skates, a turtle kickflipping a skateboard, and a dachshund driving a stretch limousine.

I'm confused. This doesn't mean they trained on it.

I didn't say trained on, I said "trained for SVG output". Gemini team members have publicly stated that they have trained for SVG:
