grammar - Is this parallel? "He's not only the Hair Club president but also a client.'

What Sy Sperling not only said in his television commercials, but also legally trademarked (!), was this:

"I'm not only the Hair Club president, I'm also a client!"(TM)

And yes, Mr. Sperling's usage was grammatically parallel. :-)
