Confused......

Thank you for the interesting article; however, it had deepen my confusion...
I understand the subject of the article is about UK not correcting ATC given altitude when temperature is colder than ISA. BUT IS IT A FACT OR A SINGLE CASE? Do i need to make a concern of ATC rv altitude next time when i go there in cold days?
from the eurocontrol document, it seems like we still have to apply correction ("these values should be add to the minimum safe altitude as appropriate"). Correct me if I am wrong...
Colder than ISA day.....
"Baro-Vnav NA BELOW -15C"
Therefore when
it is -10C.....LNAV/VNAV minimum can be use without any correction
And
It is -20C.....LNAV minimum but must apply altitude correction

I understand it is two different scenarios with EGLL "minimum temperature....." Without further explanation....
Or it could be me that is lack of the ability to understand. Tahnks
