In the picture it looks like the tip of that particular vine was broken/clipped off. If that is the case, the buds located at the leaf nodes would be stimulated to grow earlier than normal and will most likely grow vegetatively until the day length begins to shorten - at that point they should begin to 'burr'.
If the growing tip wasn't broken off, I have no idea why the laterals would begin to develop this early. Good luck.
