It seems highly likely that there is some LexedToken produced by that rule which carries the value "b" inside. As I currently can't find the referencedElements collection properly filled, I was just using <i>all</i> LexedTokens produced by the respective rule which of course are too many if we're not just executing a single production at a time.
