Please...stop muddying the issue.
1. Is it cheating to use EPO?
Answer is yes.
2. Could freezing the sample somehow skew the test so that you'd get a positive result without EPO having been in the athlete's blood?
Answer is no.
3. Is there a chance that a test following proper WADA protocols would have produced different results?
Answer is...Yes, a very very slim chance.
Those are the basic facts. Everthing else is chaff.
