No, the title clearly states an issue with high offset values, so my statement is relevant. Also, no, offset does have a max value of 1000 and was confirmed by Dallas in this post. Make that same request again with 1000 offset and you’ll get the same result.
Edit, it seems like they may have altered the behavior of offset. Regardless, if you specify a value above its apparent max, you will get incorrect results or an internal server error.
