Lego Blocks

    Hi

    The problem description says:

    • (1) It should not be possible to separate the wall along any vertical line without cutting any lego block used to build the wall.
    • (2) You cannot make a vertical cut from top to bottom without cutting one or more lego blocks.

    What is the difference between (1) and (2). Doesn't both mean exactly the same:

    • A vertical line from top to bottom intersects the interior of at least one block
