No, that's Extended or Long Term support. EOL is... the end of support altogether.
And even by your definition, what Intel is doing here is not "EOL" since apart from security updates they will receive critical updates, as in "the iGPU is not working in Win12, here's a driver to fix it". This is written in the OP.
You put a lot of faith in Intel justifying future software incompatibility as "critical" when they have still not fixed issues in current software compatibility before making this announcement.
