It is not. A certificate for *.github.io doesn't cover
See rule #2 of https://tools.ietf.org/html/rfc6125#section-6.4.3
It is also quite normal that they don't have certificates for
"subsubdomains". I don't see an option in GitHub pages to configure
further subdomains, and given that github usernames can't contain dots,
it doesn't seem such "subsubdomains" would be used, so GitHub should
probably stop resolving them.
