Green button charge redundancy?

saves between screens, which makes possible to press the button on one side on the map, run all the way through, and then BAM! the timer is still active and counts only if there is a breen block/button on a screen.

say, when you need to open some blocks with no button around

This thing is a closed door @37,17. I've found a way through 39,17 with a green button (luckily I had some time left on the green switch from somewhere... this screen also gives you an orb, the black one, if I remember correctly) and then via 38,17, but the latter one seems impassable from the right.
There is Malie's body in the water, and an electrocuting robot hanging in the air. The waterfall prevents from any jumps or anything from the right side, and there is a conviniently placed white robo-killer orb on the left side of the screen... which I can't access! Obviously, it might be accesible from the left, but the leftmost room is blocked by a door (37,17) with no button anywhere near in sight (I've got all the surrounding blocks opened).
I was pointed out that Malie is met once again during the course of the game (besides the first encounter in some green environments with fishing rods), and only after that the mentioned door opens, thus leading to her body.

Either to make 39,17 impossible to enter from the right (like adding a high ledge or something), or maybe do something with the green timer... Which strangely couns only when on-screen. Maybe all that is supposed to be a bug anyway?

bell access whatsoever... Except from the disorder maybe
