Technically it didn’t since all these tasks were done some time ago. On that note, I feel like putting a dollar amount on the tasks it was able to complete is misleading.
In the real world, if a model masquerading as a human is only right 25% of the time, its reviews on Upwork would reflect that and it would never be able to find work ever again. It might make a couple thousand before it loses trust.
Of course things would be different if they were open and upfront about this being an LLM, in which case it would presumably never run out of trust.
And again, Expensify is an anomaly among companies in that it gives freelancers well articulated tasks to work on. The real world is much more messy.
