What to do with tables that start with the same value

Heyo sorry if the title doesn’t match with the question, but I have a dictionary of moves which has a table for its sequence (the keys you need to press to perform the move) like this.

[3] = {
	Name 		 = "Grab";
	Sequence 	 = {"G","B"};
},
[4] = {
	Name 		 = "Light Punch";
	Sequence 	 = {"G"};
};

And I then have a function which is being ran every frame which checks if what was inputted matches a sequence however turns out the code messes up when there’s multiple sequence that start with the same input if I try to perform the Grab move I can’t whenever I input G it will think I’m trying to do Light Punch.

Here’s the function that checks the sequence

local function CheckSequence()
	local commandInputIndex = 0 --stores the index of the InputSequence table
	local lastMatchIndex = 0 --stores the last matching move
	local matchedInputCount = 0 --stores the amount of matching inputs

	for moveIndex = 1, #Moveset do
		commandInputIndex = ((#InputSequence - 1) + 1) --makes sure that it always stays at 1
		matchedInputCount = 0 --sets it to zero for each move in the moveset
		for inputIndex = #Moveset[moveIndex].Sequence, 1, -1 do
			--"consume" the InputSequence until it is no more or we found our target input.
			while (commandInputIndex >= 0) do
				if Moveset[moveIndex].Sequence[inputIndex] == InputSequence[commandInputIndex] then
					matchedInputCount += 1
					break
				end
				commandInputIndex -= 1 
			end
		end

		if (matchedInputCount == #Moveset[moveIndex].Sequence) then
			lastMatchIndex = moveIndex
			local move = Moveset[lastMatchIndex] 	
			--if CheckIfMoveIsValid(move) then 
			print("you performed: "..move.Name)
			InputSequence = {}
			Modules.ClientCombat:MoveInputted(move)
			--end			
		end
	end
end

My solution was to loop through all the moves and check if any move starts with the same input and if it does wait a tiny bit to see if a new input is added, but I didn’t manage to make this work. Any solutions?
