It is when the very tip of a fine edge bends over rather than wearing away. The blade still looks sharp but needs pressure to bite — and pressure is what makes a blade skid across a board.

Does that make the blades last forever?

No. They resist rolling longer than a standard blade, which means more usable working time per blade. They are still consumables.
