(2.0) Error checking when using multiple conditions

[MicroNovaX]

While using multiple conditions, the lexer does not notice the error.
Broken code: (cpu > max_cpu | cpu < min_cpu)
Working code: ((cpu > max_cpu) | (cpu < min_cpu))

for reference: Lexer splits raw text into a list of tokens Token((), ID(cpu), Token(>), ID(max_cpu), Token(|), ID(cpu), Token(<), ID(min_cpu), Token())
Here issue related to Parser (which transforms list of tokens into AST (asbtract syntax tree)).
As i understand, expected parser behavior is:

ParenExpression {
  OrExpression {
    ParenExpression {
      ID(cpu), Token(>), ID(max_cpu)
    }
    Token(|)
    ParenExpression {
      ID(cpu), Token(<), ID(min_cpu)
    }
  }
}

But actually it's not.
