Digital certificates

Almost all websites of online stores have a billing system installed. Almost everyone who has billing has a certificate for the domain on which it is installed. Billing can be set like this: example.com/billing or like this: billing.example.com. Accordingly, two questions.
1) Why, when entering the site from the first example, in 99% of cases, I am not immediately transferred to a protected page?
2) What is the beauty of the second option - to buy a certificate only for a specific subdomain, if you can protect the entire site (I do not consider wildcard certificates)?

1) Because in 99% of cases, developers don't even think about applying encryption. " SSL? Choet? Ahhh… well, no, let the admins do it, that's their job ."
2) Offhand options: a) a more secure option than certificates for other subdomains; b) if a wildcard certificate is compromised, all subdomains except this one are affected.
