Correct.

Possibly not true for this one element of this one lens. Or at least not 
amenable to the usual fungus solutions. I've heard various speculations 
about the cause, including some component of the coating on one surface 
of one element that includes something especially yummy or haze from 
some component of a lubricant. Who knows. But it is a unique problem 
with this one OM lens.
