I don't get the point why continuing by comparing the last byte is better than comparing the second byte.

Because it detects when you can skip ahead. Ie. It exactly achieves, very efficiently, only checking 100 starts when comparing a 300 byte string against a 400 byte string. No other datastructure is required.

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
