You are correct.
This is a problem with the language. The same function means different
things in different contexts with (essentially) the same kind of input.
Do you propose to fix the user confusion caused by inconsistent language
constructs (aka a language defect) by an even less consistent
i
n type and define
legal operations on this type.

I think we should consider Bag and relations to be the same so that we
can handle processing in the outer script as well as inside of nested
foreach the same and make it easi

Here is an example that I have given a while ago in JIRA Pig-158 :-
A = LOAD 'fil1' ;
B = A.($0,$1) ;
STORE B ;
which is similar to your top-level projection example.
I believe there is no distinction between so-called relations and bags in
our context.
"A top level relation is assumably spread
All,
A question on types in pig. When you say:
A = load 'myfile';
what exactly is A? For the moment let us call A a relation, since it
is a set of records, and we can pass it to a relational operator,
such as FILTER, ORDER, etc.
To clarify the question, is a relation equivalent to a bag
