Dear Morno,
Yes. I would like to get "technical" otherwise untruths and propaganda from people like you go unchallenged and garner a grain of undeserved truth.
"Push to level off" will always over ride ALT* (altitude capture or acquire to the Luddites).
Some people have problems managing high rates of climb or descent at the lower levels when traffic is a threat. If a lower rate is required whilst in ALT* then "push to level off" (if the AP is ON it is quite snappy) then select an appropriate V/S. Some companies' procedures suggest not more than 1000 feet per minute, others not more than 1500 feet per minute.
V/S is V/S. If you are below the FCU ALT and select a positive V/S then you will capture that ALT. Conversely if you are above a FCU ALT and have a negative V/S selected you will capture the ALT.
If in any doubt turn the autopilot and flight directors off and fly the aircraft.
