Even better if it's the active wallet that he used in the last session; it'll be the first wallet Electrum will load the next time he start the app.
The only problem I have with Electrum in that case is that the software doesn't mention the name of the wallet you last closed and for which it's asking you to enter a password. Electrum only shows a window saying "Open Wallet". They could also mention the name of your wallet. That will make it easier for users to remember which password is associated with that particular wallet without guessing which one they closed the app with last time.
