Noki 3 Max Coins (Glitch/Exploit)

If you die, you lose all you coins, but if you managed to get coins after Mario dies, but before the fadeout, and if you death just respawn Mario on the same sub-area, you'll keep the coins you've collected after the death, but before the fade-out for the respeawn. 

In that case, you can wait until Mario drown, and with a precise timming, get in the upwarp current and makes Mario dies before touching the 1st coin of the vertical line. With that you can collect 15 coins and make respawn all the sub-area, and then getting a max score of 65 coins instead of the classic 50 coins.

Don't know if we can call this a glitch, and if it's one, if this type of glitch is allowed for a score to be on the leaderboard, that's why i'm asking.
This glitch is possible on all versions of the game (Jap/Us/PAL)

I've joined a video with the full attempt (entering in the bottle the 1st time, dying and collecting all coins)

Hello darkman64000, and thx for providing all the intels. From what I got, anyone can reproduce the glitch on their games and it does not break any of the general rules. So the glitch is allowed, thx for checking by before posting !
Although do not forget the use of unofficial emulators is still prohibited.

Have a great game !

TY for your anwser!
also don't worry for emulators, i'm playing with an official PAL disc of the game, just using my Wii instead of my Gamecube because it's easier for me to make record of my Wii,  all records i'll submit for this game will be with an official copy of the game. I won't use any emulator for any submission
