What is EOSS(End of Standard Support )?

I'm using a DELL switch, but I'm confused about product maintenance terminology.

If you click the link below, you will see information about “Product Life Cycle (End of Support and End of Life) Policy for Dell Data Security”

https://www.dell.com/support/kbdoc/en-us/000128563/end-of-life-end-of-support-policy-for-dell-data-security

Through the link, I understood EOS (end of sale), EOS (end of support), and EOL (end of life).

However, in the link below you can see a new term called EOSS (End of Standard Support)

EOSS is not explained separately in the link. Can you tell me what the term is? Is this the same term as EOS in the existing link?
