Actually Pete, the wording is anything but vague and is very precise and clear. Don't forget these rule wordings have evolved through several iterations and have been tried and tested time and again worldwide in front of very knowledgeable juries. If you look at the wording throughout the current RRS it is clear that a lot of thought has been put into the phraseology.
To see my point have an English teacher diagram the verbiage.
With that, I am done with this particular argument. If this is the customary interpretation, I'll adapt.
