No. "reload" does not tell Squid to fetch a new copy of the page.
"Shift-Reload" does.

"Reload" is

GET ...
Pragma: no-cache
If-Modified-Since: <last-modified from last request>

This tells Squid that the browser wishes to revalidate it's cached copy
with the origin server.

"Shift-Reload" is

GET ...
Pragma: no-cache

This tells Squid that the browser wishes to fetch the complete object
from the origin source without any cache validation.

In both cases are the Squid cache completely ignored. If the request
returns new information then Squid caches this.
