What does it mean when a guy is standing in the same position as you?

i was in the grocery store and there is this cashier i like and i'm not sure but i think he might like me. well i was just leaning on the counter where the bagger bags things and i was kinda leaning in a weird position but it was comfortable, with both my hands out and positioned a certain way. well then i look out of the corner of my eye and he looks at me for a second, then looks over somewhere else, and then a couple seconds later he leans on the counter EXACTLY the way i am leaning! hands in the same exact position, leaning in the same direction, everything. what does this mean, if anything at all?
