As far as I know the name is all you need, it confirms the package was signed for, the actual signature is not necessary.
Keep in mind that with any postal delivery (except Registered) anyone who answers the door can sign. For Registered it's supposed to be the specified addressee but in my experience anyone can sign at the door, only if the item is picked up at the post office do they require it to be the addressee (even that can be circumvented). With Registered you usually don't even see the name online, only that it was delivered.
