I believe they're talking about trying to access a phone once it has been "locked" from too many wrong tries at the lock screen.

That's what I got from the article, the key was wiped because of X many tries so Apple can't "unlock" the data on the device (excluding everything backed up to apple cloud).

In the future they will use shady FinFisher iTunes and other exploits to grab the data then seize the phone.
