If you lie the tool flat over the top bars and just slip the end of the J between the top bars, rotation applies the pressure horizontally. The propolis seal is cracked this way >> instead of this way ^^.

That's why leaving space for and using a dummy board is wise - it leaves a gap for the frames to move sideways when you use a j tool Or any other lever) properly - once the frames are loosened you are free to use them however you like
