Can anyone tell me the exact meaning of EnvironmentEmulation?

One usecase can be found in Mage_ProductAlert_Model_Email

$initialEnvironmentInfo = $appEmulation->startEnvironmentEmulation($storeId);

if ($this->_type == 'price') 
 $this->_getPriceBlock()
 ->setStore($store)
 ->reset();
 foreach ($this->_priceProducts as $product) 
 $product->setCustomerGroupId($this->_customer->getGroupId());
 $this->_getPriceBlock()->addProduct($product);
 
 $block = $this->_getPriceBlock()->toHtml();
 $templateId = Mage::getStoreConfig(self::XML_PATH_EMAIL_PRICE_TEMPLATE, $storeId);
 else 
 $this->_getStockBlock()
 ->setStore($store)
 ->reset();
 foreach ($this->_stockProducts as $product) 
 $product->setCustomerGroupId($this->_customer->getGroupId());
 $this->_getStockBlock()->addProduct($product);
 
 $block = $this->_getStockBlock()->toHtml();
 $templateId = Mage::getStoreConfig(self::XML_PATH_EMAIL_STOCK_TEMPLATE, $storeId);


$appEmulation->stopEnvironmentEmulation($initialEnvironmentInfo);

My understanding is that everything betweenstartEnvironmentEmulation and stopEnvironmentEmulation is treated as under the storeId that was given as an argument.

But when I look at the example, the templateId takes the storeId directly as an argument. So there would be no need for en emulation here.
Am I right?

So far my only guess is, that there is a function deeper down in one of the methods that get the current store with something like getCurrentStore?

Thanks in advance :)

If a task is executed in an emulated environment it will take the related store scope translation, configuration settings etc.
