spell-bound?

One of today's Supreme Court decisions, as reported by CNN.com:

"The Supreme Court has again given police greater power to stop and question suspects, ruling Monday that a Nevada cowboy could not refuse to give his name to officers who tried to question him along a roadside.

Larry 'Dudley' Hiibel, the Nevada rancher at the center of the case, had become a minor celebrity for those who believed he was standing up for his constitutional rights.

He was arrested after he told a deputy that he didn't have to reveal his name or show an ID during an encounter on a rural road in 2000.

Okay, so the court ruled that Hiibel was legally obligated to tell police his name so they can run it through their computers and see if he is wanted for a string of serial murders or being an opposing soldier in the War on Terror or whatever. My question: with a name like Hiibel, is he obligated to spell it for them? Or can he let them try to figure out how to spell it, which, given the probable pronunciation HY-bull, isn't likely to be a spelling they come up with on their own.

What if they he and the police officer had this exchange:

"What's your name?"
"Larry Hiibel."
"HY-bull. How's that spelled?"
"Like it sounds."
"H-I-B-L-E?"
"You have the L and the E switched around."

Is he in violation of the law then? Or, what about:

"What's your name?"
"Larry Hiibel."
"HY-bull. How's that spelled?"
"H-I--are you writing this down?"
"Yes."
"You got that it starts with H, right?"
"Yes."
"Well, then: I-B-E-L."
