 In F#, the order of declarations matters, including with `open` statements. This is unlike C#, where the effect of `using` and `using static` is independent of the ordering of those statements in a file.
 
-In F#, because elements opened into a scope can shadow others already present. This means that reordering `open` statements can alter the meaning of code. As a result, sorting alphanumerically (or pseudorandomly) is generally not recommended, lest you generate different behavior that you might expect.
+In F#, elements opened into a scope can shadow others already present. This means that reordering `open` statements could alter the meaning of code. As a result, any arbitrary sorting of all `open` statements (e.g., alphanumericall) is generally not recommended, lest you generate different behavior that you might expect.
 
 Instead, we recommend that you sort them [topologically](https://en.wikipedia.org/wiki/Topological_sorting); that is, order your `open` statements in the order in which _layers_ of your system are defined. Doing alphanumeric sorting within different topological layers may also be considered.
