The section that not > say that > symbol properties such as "value" have a global context. It is symbols themselves that are global objects. It follows that their property values are also. (Of course, a Lisp value can be shared.) Symbols are stored in obarrays. By default, they are stored in the obarray that is the value of global variable `obarray'. So you can have two symbols with the same name (the name is just one of a symbols properties, its `symbol-name'), but which have different values for other properties, such as `symbol-value'. E.g., you can have two symbols `foo', in two different obarrays, with two different values when used as a variable. (They can also have different `symbol-function' value, etc.)
