An ordered list of tokens is not sufficient for describing a match in a MultisetSubstitutionSystem. For example, the following misses the match corresponding to {a -> Sequence[1, 2], b -> 3}:
MultisetSubstitutionSystem
{a -> Sequence[1, 2], b -> 3}
In[] := #["ExpressionsEventsGraph", VertexLabels -> Automatic] &@ SetReplaceTypeConvert[{WolframModelEvolutionObject, 2}]@ GenerateMultihistory[ MultisetSubstitutionSystem[{a__, b__} /; OrderedQ[{a, b}] :> {{a}, {b}}], {"MaxGeneration" -> 1, "MinEventInputs" -> 3, "MaxEventInputs" -> 3}, None, {"InputCount", "SortedInputTokenIndices", "InputTokenIndices", "RuleIndex"}, {}][{1, 2, 3}]
The system should generate two matches.

This requires some rethinking of the multihistory data structure.
The problem
An ordered list of tokens is not sufficient for describing a match in a
MultisetSubstitutionSystem. For example, the following misses the match corresponding to{a -> Sequence[1, 2], b -> 3}:Expected behavior
The system should generate two matches.
