Is it possible to have the same wallet on 2 separate computers for the same DIVI?
Yes, however, it is not suggested.
Unless you have perfectly identical setups(clones), a seed restore is not a cloned wallet.
A setup includes at minimum three items:
wallet.dat(copy of original wallet)
The other catch would be this: never transact on the secondary cloned wallet. Or at least be aware that your address pool (Immediate list of addresses) will diverge at a later date.
Nothing is ever at risk; however, people who do this can become unsettled or confused if they don’t understand the nature of an HD wallet, seed phrases, and address pools.
