Very broken server, by the way (see later).

By default, dig queries only records of type A. They work at
drama.org.

host queries also AAAA and MX record types. Hence the three requests,
and, since the authoritative name server is broken
(record-type-dependent lameness), the two SERVFAIL from your recursor.

(Discovered with tcpdump and confirmed with dig.)
