The meaning of the term 'cul-de-sac' doesn't just mean dead end road or no through road. In some cases (and in this case) it's referring to a dead end road with a turning circle at the end.
https://en.wikipedia.org/wiki/Dead_end_(street)Here's one such definition
"a. A dead-end street, especially one ending in a circular turnaround.
b. A circular turnaround at the end of a dead-end street."

https://www.virginiadot.org/projects/resources/appendb.pdfYou will see that some dead end roads terminate in T-type and branch type turnarounds, but the type referred to in Rocío's text is a bulb cul-de-sac.
Here's a description of how to pave a cul-de-sac and a video too. They only refer to the bulb shaped turnaround part at the dead end of the road.
