Wording for label selectors / selectors with requirements in Selector documentation

[tom1299]

I was just going through the documentation on Labels and Selectors. And in the section on Label sectors it says:

A label selector can be made of multiple requirements which are comma-separated. In the case of multiple requirements, all must be satisfied so the comma separator acts as a logical AND (&&) operator.

So as far as I understand it, a single selector can contain one or more Equality-based or Set-based requirement.

Further below in the paragraph LIST and WATCH filtering it says:

For list and watch operations, you can specify label selectors to filter the sets of objects returned;

Not the plural for the term selector"s". Shouldn't that just be "you can specify a label selector" ? Because it is actually a single selector with multiple requirements ?
