MQMT_SYSTEM_FIRST is a range identifier and will never be used in a real message. If you see the value 1 in an MQMD, it always means MQMT_REQUEST.

So in effect you have MQMT_SYSTEM_FIRST -> MQMT_SYSTEM_LAST as a reserved range for system MQMT* values and MQMT_APPL_FIRST -> MQMT_APPL_LAST for application use.
