why $.Resource and .Resources not same? Is it a bug or design behavior?

Hugo version : v0.136.1

{{ $related := first $params.related.count (where (where $.Site.Pages ".Params.tags" "intersect" .Params.tags) "Permalink" "!=" .Permalink) }}
{{ with $related }}
    {{ range . }}
            {{- $resource := .Resources -}}
            {{- with "aaa" -}}
                {{- fmt.Warnf "related  $.Resource is %v +====== before .Resources is %v " $.Resources  $resource -}}
            {{- end -}}
    {{ end }}
{{ end }}

output:

https://gohugo.io/templates/introduction/#context

You should read that page, and the “Context” section in particular, before you begin templating anything.

Make sure that you thoroughly understand the concept of context before you continue reading. The most common templating errors made by new users relate to context.

I misunderstand ‘$’ as getting the parent variable :cry:

A couple of examples…

{{ range slice "a" "b" "c" }}
  {{ . }} --> a then b then c
  {{ range slice 1 2 3 }}
    {{ . }} --> 1 then 2 then 3
  {{ end }}
{{ end }}

{{ range $foo := slice "a" "b" "c" }}
  {{ . }} --> a then b then c
  {{ range slice 1 2 3 }}
    {{ . }} --> 1 then 2 then 3
    {{ $foo }} --> a until we start the next iteration of the outer loop
    {{ $.Title }} --> returns the Title from the Page object
  {{ end }}
{{ end }}
