In several places in the iOS Apple Watch settings app, important functionality depends on "you" wearing the watch. Critically under the settings for unlocking the watch without requiring a passcode (Security > Unlock with iPhone):
When this is on, unlocking your iPhone will automatically unlock Apple
Watch — as long as you're wearing it.
Does the Apple Watch really form a signature for recognizing a specific user (analogous to fingerprint recognition), or should the above read "as long as someone is wearing it (in BT range of your iPhone)"?

As far as I can tell its just means as long as it's connected via bluetooth and in range. There isn't a Touch ID scanner on the watch or anything like that so I don't think that it forms an knid of "signature" to you.
