It should. All have something like:
| :Skein-512:   512-bit hash, msgLen =     8 bits
512 algo, 512 output. 

The third one has:
| :Skein-512:   512-bit hash, msgLen =  2040 bits. Tree: leaf=02, node=02, maxLevels=02
So it looks like the same except that it has the "Tree: leaf node"
attribes as well. So maybe this is something special maybe not. As I
browsed the .txt files for other vectors I did not find any where msglen
wasn't a multiple of 4 bytes (except some odd ones where msgles was 7
bits). Maybe I did not look close enough.
