Your understanding that only the focused view (among views) can be first responder is correct. This is reflected in "responder" being singular and not plural.
Imagine a window with several NSTextFields. Imagine Edit > Select All being selected. This sends a selectAll: message to the first responder (and up the responder chain until a handler is found, or the chain is exhausted). Making every NSTextField the first responder would make the effect of the select-all indeterminate, which is undesirable.
