'''SplitTemporaryVariable''':	''"You have a temporary variable assigned to more than once, but it is not a loop variable or a collecting temporary variable. -> Make a separate temporary variable for each assignment."''

From page 128 of RefactoringImprovingTheDesignOfExistingCode book:

-----

Typical symptom:  A single variable has different meanings in different parts of a method.

Conclusion:
	1. The method is too long.
	2. You need two variables; one for each usage.
