Why switch around insertion and deletion costs? #15

Is there some specific reason for switching around the insertion and deletion costs like this:

function levenshtein(source::AbstractString, target::AbstractString, deletion_cost::R, insertion_cost::S, substitution_cost::T) where {R<:Real,S<:Real,T<:Real}
    return levenshtein!(target, source, insertion_cost, deletion_cost, substitution_cost)
end

I find it mildly confusing when reading the source.
