He hasn't called at all. He's checked: http://en.wikipedia.org/wiki/Betting_in_poker Check If no one has yet opened the betting round, a player may pass or check, which is equivalent to calling the current bet of zero. When checking, a player declines to make a bet; this indicates that he does not wish to open, but does wish to keep his cards and retain the right to call or raise later in the same round if an opponent opens. In games played with blinds, players may not check on the opening round because the blinds are live bets and must be called or raised to remain in the hand. A player who has posted the big blind has the right to raise on the first round, called the option, if no other player has raised; if he declines to raise he is said to check his option. If all players check, the betting round is over with no additional money placed in the pot (often called a free round or free card). A common way to signify checking is to tap the table, either with a fist, knuckles or an open hand.
