Well, you might care...

a = (1,)*(10**12)
b = (1,)*(10**12)
c = (1,)*(10**12)


Each of those tuples would require a rather lot of memory. The difference
between "a lot" and "three times a lot" could be significant.

But other than memory efficiency, yes, you are correct, there's no real
reason to care about the difference between the two cases.
