That's Roblox, not Minecraft. Similar aesthetics, true, but different game.
I guess if you paint with a very broad brush, you can say that Fox, Pikachu, Mario, and Luigi's neutral-Bs are fundamentally the same move because they are projectiles. Probably not a good example.
What would be a hypothetical scenario where we get "a file cabinet of variants of the same move"?
(My apologies for the delay. I was writing up this long-winded answer, but ended up lost, and I realized how late it was, and started being unable to concentrate properly, so I cancelled it)
Define the coin jump to satisfy these four properties:
1. Mario jumps into the air anywhere between 60° and 90°
2. Mario strikes the opponent a variable number of times depending on proximity to the opponent (Luigi is a special case where this number is 1.)
3. The opponent is launched upward and/or outward.
4. Mario descends at constant speed after launching the opponent.
Suppose that in the next Smash Bros., a number of newcomers have up B moves that satisfy the same properties. Using the minimum number of newcomers to exhaust all of the possibilities, each one tweaks the move by a difference of 1° rise angle, 1 strike, 1° of launch angle, and one unit per second of fall speed from another newcomer or Mario. Assuming these laughable nuances were included, the player may not distinguish so well the difference between any two but the most removed newcomers during normal play. Any move that can be called a coin jump would have different figures associated with them, but would fulfill all of the requirements above. The file cabinet comes in when we reiterate a move that satisfies these same four minimum requirements, with only minor differences between them. (I wish I had the 'steam' to give a more sensible answer, but at the moment, this is the best I can conjure.)
