Basically when you’re pushing toward the bridge you’re stretching the string area toward the nut, pushing “extra” string slack toward the bridge, making the note flat. Then when you pull toward the nut, you make the note sharp. It’s because of the drag between your skin and the string.
Nylon strings are thicker and have a lot of drag, and if you try to vibrato vertically on a nylon the string tends to “roll” and it’s not ideal. But you can do it on steel strings just the same.
Incidentally I talk about this string drag when adjusting intonation all the time, and what “perfect” intonation is. It’s dependent on the player. I can show someone how if you slide up to a note, it will be flat, if you slide down to that same note it will be sharp.
