“ra” and “ist” are part of the word in process, just being done out of order for creative flair, as you noted. “Sa” on the other hand, is its own thing and isn’t a word. Doesn’t mean it couldn’t be there though as it would have to be challenged to be removed.

That said if I had a 6 letter word with that bonus I wouldn’t challenge homey on like 2 points. I’m dumb, but I’m not stupid.
“Ra” or “Re” is the ancient egyptian god of the sun “ist” means “is” in german “sa” can mean lots of things in lots of languages
“Sa”, as previously noted, is not an accepted Scrabble word. Abbreviations are not acceptable in Scrabble. Foreign words aren’t accepted in Scrabble so “Ist” and, “Sa” would be out there as well as it appears we’re playing English Scrabble. “Ra” is also not accepted in Scrabble as proper names (like, “Thor” for another example.) are not accepted.
More importantly, words need to connect to an existing word so, “ra”, and, “ist” by themselves wouldn’t be accepted on those grounds, hence the determination that the person played them on their turn and is actively tying to figure out which letter they should use for the middle bit to finish the single word on a single line they can play on their turn.

I doubt it was intentional, but it feels kinda fitting.
