I do this in conversation. It's easier to say "jab" than "light punch". Also less awkward to say. That's just the way I feel.I mean some people still use fierce and roundhouse instead of HP and HK
Similarly, I feel the same about "two A" vs "crouching jab" or "crouching A", but that's just personal preference than any real perceived advantage. I guess you do save yourself, like, a fraction of a second saying one versus the other.
