Even when people provide “in progress” glimpses of their work, it’s not really in progress. What you’re seeing is just a carefully chosen snapshot of what they’ve recently done.
My text buffer is a mess. I have seven lines that are in progress at the end of this document, two of them identical, and two more of them identical (they’re in pairs!), but one of them a dribbling sentence about sausages and shame, none of which has anything to do with the story in any context.
If someone glimpsed over my shoulder, right now, and saw what havoc had become of my document, they would close their eyes and shake their head in amazement.
