That next to last bullet point in the article is particularly important. Water pressure at 1.5 meters is 2.11 psi (plus the 14+psi of air pressure above it, of course). That's not much. It's like dropping the phone from about 1/4". Dropping it from a higher point
can force water into it ir it falls not quite flat.
So
will it be okay? No one can say, but read
Oh, no! My Phone got Wet! for more information on what you
should have done.
(And in the future, keep the phone out of the bathroom. Steam can get in even with an IP68 rating - the rating is for standing
water at room temperature. Retrieving a phone from an unflushed toilet isn't a job anyone looks forward to. You really don't need the phone surgically attached to you.)
