I see.
I thought that the MAC address was used to change the MAC address and not to select the card.
Wouldn't it be easier to enter the interface name?

Anyway now I've create 2 entries with different MAC and it works.

What is misleading is that there are one list of networks per card, so one expects that the network 
is connected only on the selected card. Shouldn't NM set the MAC address automatically when it 
create an entry automatically?
Or there should be only 1 list of all networks available regardless of the card.

No, I mean ifconfig, and what I check is that there is an IP number or not for each interface.
I don;t use the SSID from iwconfig since as you say it does not mean "connected".

Something like a radio button, so there can only be 1.
