I am lost sending coins from this multisig wallet.

I use an online watch wallet to create an unsigned send txn, save it to a usb drive.
load unsigned txn into multisig1  , sign it , save and export to usb drive.  (what is the difference between save and export ?)
load signed txn into multisig2. There is no sign option(greyed out) then what ?

I got it to work once after much fiddling, but not sure how to repeat. It is completely un-intuitive and unhelpful IMO.

Update : It gets worse, I tried 3 methods to send the coins , all 3 different, all 3 worked, at least 1 was wrong(1 sig) it still confirmed. Now I'm worried ! I conclude that this does not achieve 2of2 in electrum. You can pretty much do anything as long as you have at least 1 sig, it will confirm.

PS : It says 2of2 at the top of each wallet and I used the other's key to create each multisig wallet respectively. Presumably they are correctly setup.

Test1

1. Online watch wallet-send txn , export to usb
2. Offline multisig1 wallet-load unsigned txn,  sign, save, export
3. Offline multisig2 wallet- load unsigned txn, sign, save, export(this overwrites the prev signed txn file from multisig1 wallet )
4. Load signed txn file from step 3 onto watch wallet and broadcast

Test 2
Only signed on 1 multisig wallet and then broadcast from watch wallet. (sent and confirmed only 1 signature !)

Test3

1. and 2. are the same, but 3. I just loaded the signed txn and then saved and exported it back. Sign button was greyed out.
