There is no ambiguity. See the language reference:

"Formally, if a, b, c, ..., y, z are expressions and op1, op2, ..., opN
are comparison operators, then a op1 b op2 c ... y opN z is equivalent
to a op1 b and b op2 c and ... y opN z, except that each expression is
evaluated at most once."

The last restriction (single evaluation of involved expressions) makes
this a bit more than raw syntactic sugar.
