Yes, you're right, it behaves that way. It might very well be that there indeed is a bug hidden (although it still makes interesting sounds... ;)
Well I compared your code against the formula in the paper, and I couldn't find any differences - it looks like it matches to me.
The only minor error is that H is the number of harmonics minus one, so that H=0 should give a single frequency, not H=1. I guess you could say that it's the number of overtones.
I tried to convince myself using trig identities that with H=0 and a=1/2, that big mess simplifies to a sinusoid. But so far I haven't been able to do that yet. But I'm not a mathematician, so this doesn't in itself mean a problem.
Still, I suspect that there's an error somewhere in the paper as published.
Well we should look at the csound buzz opcode I guess...
