Or maybe "Teller (magician (of duo Penn & Teller (known from Fool Me (a British TV show)))) reveals his secrets"
Just because you would have preferred a story of a bank teller… and had it been this way, another one like you would have complained that it's not about the famous magician.
Language is ambiguous. "Teller" is his name, there is no conceit in the headline.
And as long as there is no conceit, your accusation is out of place.
