It is correct behavior, and is documented though perhaps not as explicitly
for this exact combination.
>From spec.txt, section 11.7 underneath the definition of match_local_part:
This condition, together with match_address and match_domain, make it
possible to test domain, address, and local part lists within expansions.
Each condition requires two arguments: an item and a list to match.
...
In each case, the second argument may contain any of the allowable items
for a list of the appropriate type. Also, because the second argument
(after expansion) is a standard form of list, it is possible to refer to a
named list. ...
The idea is that match_address may contain any of the allowable items
for an "address list". Address lists, defined in section 10.19, can
contain full addresses, domains, etc. There are a number of examples
of what can be included in 10.19.
If you really need to match an address exactly but are concerned about
the allowable formats in an address list, you could use either an
exact comparison or perhaps a regex match:
${if eqi{${address:jh@???}}{jh@???}{true}{false}}
${if match{${address:jh@???}}{\N^jh@???$\N}{true}{false}}
If you are pulling an address out of a From: or other header, be sure
to use the ${address:XXX} tag, as shown above, to strip the email
address out of RFC2822 address format.
Hope this helps.
