With mac-address you restricted Connection 2 for the MAC. However, Connection 
1 is not restricted and that's why it can be activated on any compatible 
device. If you want only to use Connection 1  on Device 1, restrict it with 
MAC the same way as Connection 2. You can also disable auto connecting for a 
connection, if you want.
