Finish-to-start question


I have a question regarding the "finish-to-start" relationship:

"A schedule activity may begin 10 days before the predecessor activity finishes."

Why this is an example of "finish-to-start" relationship? The successor actually starts 10 days before the predecessor finishes, not that the successor starts after the predecessor finishes. So I am very confused here.

Thanks for sharing your feedback!
