This understanding is wrong. There is no difference in how '.' and ':'
index the table.

The only difference is that ':' automatically passes the table on its
left as the first parameter to the function being called.

foo.bar(foo, 1, 2, 3)
foo:bar(1, 2, 3)

are exactly the same, having nothing to do with metatables.

Hope this helps,
