I thought that tape worms reside or attach to the intestinal wall (and
not the stomach wall) and therefore when the worm leaves the cat it's
by way of the stool.

So is it normal, or unusual, for the worm to be vomited out?

It's not common, but it's normal. I had a large gray cat named Purr
Baby. He' throw up tape worms from time to time when he got older.
He passed last month.

Our vet said a tape worm had to be pretty long to get barfed up. They
looked like large rubber bands covered in bile.

If you cat is older, consider checking him for other parasites.
Consider giving him a B-12 shot since tape worms deplete B-12. It
helped Purr Baby a lot.
