If I put this "hard coded" boolean expression to a formula node in XPresso tag

(11 > 10) and (9 > 10)

then the formula produces an output of 1 (TRUE), but it should be 0 (FALSE).
However, the expression

(11 > 10) == (9 > 10)

produces the right output of 0 (FALSE).

Is it a bug in the Formula node or I do something wrong?
