You can actually turn that off. It's a preference on your account settings page, and you can override that per scheduled tweet... :)

Interesting. So what does it say when you override it? "From web"? Isn't that hard to accomplish via API?

It indeed says "From web", which is the standard if you don't provide a source parameter to the API. So it's not that hard :)
