Exporting private keys from multisig wallet?

So I've been messing around with multisig on Electrum and trying to figure it all out. My question is about exporting private keys. For example, I created a 2-of-2 multisig wallet. Then I took the compressed private key from the export section from each wallet, from the same address. Then, I went to bitaddress.org and put the private key into it and got the public key for each of the 2 corresponding keys.

I assume that I need to combine these 2 keys to output the corresponding multisig address. So I decide to use the multisig address tool on coinb.in to see if they correspond to the correct multisig address. Well when I enter the 2 public keys, it outputs a totally different multisig address than what the originally private keys were linked to and is in my wallet. I tried this with the private  keys of addresses with a 2-of-2 wallet and a 2-of-3 wallet. I can't get them to match.

So I guess my question is what am I doing wrong and how do I properly export the keys needed to retrieve funds? This is my first time using multisig.

The order of the keys on coinbin matters. Try a different order and you'll get a different multisig address.
