The Spanish goverment have been doing this equivalence for at least 15 years, nothing new.
If you read it properly you will see it says they will convalidate the " titulo de piloto". Thats a yellow paper the Spanish authority gives you when you finish your license ( invented by them). That means no joy for those of us who do not have or never held a Spanish license. Thats the answer the COPAC gave me several times between 2002 and now, and they are not willing to help with the convalidation unless you have this paper.
Goodluck
