And/or vice versa

Should one write "and vice versa" or "or vice versa"?

Examples:

A) Autocomplete can be set to 'on' for the form, but 'off' for specific input fields, and vice versa.

B) Autocomplete can be set to 'on' for the form, but 'off' for specific input fields, or vice versa.

I'm sorry about the examples, they look weird out of context. I was wiring an HTML5 tutorial when the question popped into my head.

Solution 1:

The key is useless without the lock, and vice versa.

= The key is useless without the lock, and the lock is useless without the key.

... BUT

You can put on the cream before the strawberry jam, or vice versa.

= You can put on the cream before the strawberry jam, or [you can put on] the strawberry jam before the cream.

Solution 2:

@EdwinAshworth has given examples that demonstrate how it's possible for there to be a significant difference in meaning between and vice versa and or vice versa but in your example there is not much difference. Whichever conjunction you use, the reader can be in no doubt about what is possible.

I think your use of the passive voice is a greater impediment to clarity. When you say

Autocomplete can be set to 'on'

it's unclear who can set it. If you say

You can set autocomplete to 'on'

there's no ambiguity.
