Why then is there a reference to EoL here?
What is it that you actually want to know?
FreeBSD is a professional open-source OS. Users expect to know in advance some basic properties about its support and development cycles: FreeBSD is continuously being improved and further developed. Planning ahead where possible is important.
Resources are not infinite. FreeBSD has its own development and support cycles; these are not the same as most other Unix-like OS-es. FreeBSD has a support and development cycle for its base as a fully functional complete OS, and it has a
different support and development cycles for everything from the ports tree such as packages.

LTS support and version clarifications.
For more than a year ago FreeBSD has announced a change in its development and support cycle, an important change is the shortening of its support for a major version branch, that is FreeBSD 14, 15 etc.: it will be changed from 5 to 4 years. This is a change in order to adapt more quickly and introduce improvements on the basis of shorter update cycles (see
Change to FreeBSD release scheduling and support period, 11 Jul 2024 from Colin Percival*)
Another change that is significant, is the official introduction and full support for pkgbase as the binary update management mechanism for the FreeBSD base install starting with FreeBSD 15. Colin Percival explained this is at BSDCan 2024, June 2024:
