Why did Zac globalize the variable $page in the first example function named custom_wp_title? Can't figure this out.

Why did Zac globalize the variable $page in the first example function named custom_wp_title? I can't figure this out why he puts global $page in the function as he never does anything with $page after he globalizes it. Would the function still work without it or am I missing something? Thanks!

I guess that the is_home() and is_front_page() use the $page information. Since he create new function, is_home() and is_font_page() can't access the $page info unless you globalize it in the function.

I can't find the documentation for this issue so I'm not 100% sure. Please correct me if I am wrong.
