Why Did The Pokemon Company Tweet An ILLEGAL Shiny Enamorous?

Pokemon Company twitter posted a video about Shiny Enamorous in an Ultra Ball to promote Valentines Day I guess, problem is that is an impossible Shiny Enamorous... Pokemon GO Enamorous isn't available yet and Pokemon Home Shiny Enamorous Mystery Gift can't be in an Ultra Ball. How did the Pokemon Company mess up that bad?
