That is not possible. They were lying to you. You can't see the other's review until you post your review or the review window expires. You can never change your review once posted (though you can comment on a review someone else left).

They were very pushy about asking "are you going to give me 5 stars?" before/during the stay, and saying things like "my business depends on 5 star ratings". Obviously there are lots of paths out of that situation that don't involve someone giving them 5 stars, but I'm sure it works on people.

Edit: it did not work on me

How were they planning on doing this? They don't get to see the rating you gave until after their review of you is finalized, and vice-versa.

I'm curious how they enforce this. I've never used airbnb but what's to stop a host from reading the reviews from a guest account instead of their host one? I'm assuming they're still published publicly but maybe I'm wrong?

The review isn't visible to anyone until the period expires. It's not just hidden from the specific host account.

Ah ok thank you for the clarification.

See my other reply in the thread, but basically, they were doing a lot of stuff that at first seemed like proactive customer service initially, but later seemed much more like scouting to determine if i was going to give them 5 stars or not.

Not all guests know that ratings are hidden until reviews are completed. And for those that know, maybe they were planning on guilting them into it?
