  Yeah it's an interesting object lesson in design or user behaviour or something – I notice this come up relatively often – I think because it's rarely used, or almost exclusively in certain circumstances as you say, people infer a stricter rule/possibility than anything it actually says ('If there is a url, text is optional.').
