DT is not a permanent difference, it is a temporary difference.
If company with DTA (loss carried forward) contiunes business with losses instead profit, it is very likely that the tax assets will not be used. Also in many legistalives loss carried forward (DTA) may be used within certain period, after which maturity the “tax assets” is partially deleted. This is also the reason for cautiously approach for showing such assets in the balance sheet or the formation of allowance account under USGAAP. It is always significinat probabilty that it will not be used in full.
However situation with “diminishing” DTA (loss carried forward) cannot be applied if company reverses to grow thus doing business with profit in further period in case of DTA that will be utilized.
So, not reversed amount in this case may happen in DTL position (opposite influences to utilization than DTA). Therefore, I would agree with cpk123 to assumption that company may continue (due to its super growth phase) purchasing assets and using accelerated depreciation method for a tax purpose. IMO,by IFRS application only a company also may contiune with assets revaluation indefinititely which will lead to fact that DTL would never been settled to current tax liability in case it should be recognized as equity.
