Because calling a table(...) invokes __call(table, ...), NOT __call(...).

Would be cool if type() had extra fields:

type(3) -> "number:integer"
type(3.0) -> "number:float"
-- etc... OR: (mostly backwards compatible)
type(3) -> "number", "integer"
type(3.0) -> "number", "float"
type(setmetatable({},{__call=print})) -> "table", "callable"
-- etc

But then it would become more of a capability test thingy...
