DCB Loading HDFC Forex card using HDFC credit card?

[ankiiiii]

I have read in a couple of old threads on Reddit that an HDFC Forex Card can be loaded using an HDFC Credit Card and these transactions are eligible for reward points.
That sounds too good to be true to me!
Can anyone confirm if this is accurate information?

If this is true, I will never again use 0 forex credit cards and simply load forex cards using my Diner Club Black credit card.

Thanks!
