Why is the manualResultPrice not changed until the next calculation?

Question

I observed the following PGI behavior connected to manual overrides: when the ManualPriceExpired goes 0>1 during the calculation, the manualResultPrice is not changed until the next calculation... I've checked the source code and I wonder if those two conditions should be in a reverse order?

AbstractPriceGridCalculationTask.java - public void processPGIResult

if(pgi.getManualPriceExpired()) 
   pgi.setManualResultPrice(null);

if(expireManualResult && pgi.getManualResultPrice() != null) 
   pgi.setManualPriceExpired(true);

Answer

There was a requirement to do this in two steps so that users have a chance to notice it. If the manual price was just erased, it may confuse users ("why is my manual price gone?").
