re: OT Driving experts - what does this road sign mean to you? (updated with pics)

Using your link and backing up to sign I thought it was in regards to the split immediately after the sign. It looks like 3rd lane from the right has option to go right or left, but first two from the right have to stay right. Although it (using pictures) does not look like an exit (by staying right) and probably should have used different verbiage, but I don't know area or street.
