There is an issue with logical function "and" when used in expression

There is an issue with logical function "and" when used in expression rule.
e.g. use below code in expression rule
fn!and(
ri!test1 = true()
ri!test2 = true()
)
Ideally, it should give syntax error as comma is missing after first condition. But SAIL designer does not throw any error and it evaluates the expression with wrong output
i.e. if inputs ri!test1 is true() and ri!test2 is false() in above expression rule then it gives output result as true() which is incorrect [correct output result is false()]
Now try below expression syntax (observe comma) which gives correct expected output result:
fn!and(
ri!test1 = true(),
ri!test2 = true()
)
My question here is about behavior of above expression (w/o comma):
Is this expected behavior in terms of checking for syntax errors? [not throwing error for missing comma]
If yes, please explain me how it is correct.
If no, then please consider it as a bug and fix...

Thanks for the feedback on our product. I agree this seems to be inconsistent behavior and will pass it on to our product team. In the meantime, the workaround to ensure correct evaluation will be to ensure to use the comma.
