Juan, because of the way that the plies run at 90 degrees to the adjoining plies, plywood does not expand the way solid wood does. The glue between the plies holds the wood from moving but there is a slight thickening with the changes in moisture/humidity. You can butt one sheet up to the next one and, in fact, the plywood that comes milled with tongue and groove joints on the edges show that this is acceptable.
