I assume it's a typo or equivalent mistake.
EMV (chip cards) can have a small amount of local smarts, so it is typical for example to insist on going online for a large transaction or if the card has performed too many offline transactions since last going online. The card maker decides these rules, so the bank gets to ensure the cards it issues to customers meet whatever requirements it has decided upon, balancing fraud risk against problems with loss of connectivity or services being down.
So I doubt they'd bother doing some sort of ad hoc revocation technique.
