So far all I see from POSIX is that it doesn't say anything about whether HOME is absolute or not.
By not saying anything POSIX gives permission to the application to set HOME to a relative name. When POSIX intends the requirement that an environment variable's value must be absolute (e.g., PWD), it says so. When it doesn't intend such a requirement (e.g., HOME, PATH, SHELL, TMPDIR) it says nothing.
