Why don't the lines start at the point they were in december of one year in january of the next?
They seem ok to me, except there I agree there is a bit of a jump between where the brown line ends and the orange one begins.
I assume it's just price change across the New Year holiday.  These are closing prices, so they can jump a few percent from one value to the next.
I looked fast and there seemed to be a pretty significant difference, but now that I took the time to look again I see that they match.

Optical illusion, I suppose..?
