Transit visa for Indian National through Singapore

I am an Indian national living in the United States of America under a non-immigrant (F1) visa. I am travelling to India later this year. My round trip to India has Singapore layovers on both the outbound and inbound legs. I was wondering if I could use the 96-hour VFTF for both the legs. I am aware that earlier Indians were allowed the VFTF on only one leg of a round trip. But checking the ICA’s website I find that there is no such requirement (at least not immediately evident to me).

Layovers are 9 hours and 45 minutes while going to India and 4 hours and 35 minutes while returning. I am flying with Singapore Airlines.
