[rules-users] Documentation Error?

There might be an error in Reference Manual, Chapter 10, Example 810..3: "RuleExecutionSet ruleExecutionSet = ruleExecutionSetProvider.createRuleExecutionSet( reader, properties );" The variable "reader" was not defined in the sample, should it be drlReader instead? Also in the paragraph above, the opening sentence "ruleExecutionSetProvider.createRuleExecutionSet( reader, null )" quoting from the prior example should be "ruleExecutionSetProvider.createRuleExecutionSet( drlReader, null )" as in the example.
