At first the idea that a $1000/hr associate planted a typo or two intentionally made me laugh but the more I think about it the more I think that's exactly what someone playing 4D chess with a lawsuit like this might do.
I doubt it. I've been involved with a similarly priced law firm once for an investment in a company I had a small stake in. They misspelled the names of multiple people, fixed it in the next draft version after it was pointed out to them, and then had it pop back up in some of the names a few versions later.
I know more than I'd like to about this topic; I spent most of a decade supporting legal document management systems.
Large law firms use document management systems[0] to store their documents. It's a really primitive VCS that integrates with Microsoft Office. The user who checks out a document usually has exclusive access to it until it's checked back in. Other people can check out a copy of the same document, but it won't usually contain any changes the other person made. There's additional work required and many users don't know how to do this. It's common for changes to be lost or a partner to have the help desk unlock documents. I'm guessing that's what happened in this case.
Yeah it's probably more likely they just need to bill 80 hours a week or whatever amount not to get fired and were going too fast to notice the error :)
