Not necessarily. If you have other plants in your garden (Flowers, shrubs, etc.) you will not need two apple trees. If you have no other plants in your garden, then yes, you will need two apple trees to pollinate.
These plants produce biochemicals that can actually influence the growth of other plants. So, when these plants want space they can influence other plants not to grow near that space, to grow smaller so they can not compete for that space or even in some rare cases have the plant put all it's resources into either reproductive structures or growth so it can not be successful in one or the other.
