Because the "accel" flag tells Squid to behave like th authoritative web server for all incoming requests. When it needs auth it sends a web-server auth challenge (linked to domain name by the browser to prevent XSS credential loss). Not a proxy challenge (linked to the proxy IP or user session by the browser). To require a second http_port line without "accel" that browsers are configured to connect to for regular proxy access.
