Temporal vs. All-Current: Profitability Ratios will, net, different, determine, currency

Temporal vs. All-Current

For 1) net profit margin 2) ROE and 3) ROA...

...The reason we cannot determine which (ratio for temporal or all current) will be higher/lower between Temporal and All Current under appreciating/depreciating currency scenarios....

...is because net income and equity will be "mixed" balances due to different rates used under Temporal?

Is that understanding correct? Thanks in advance.
