You are confusing things.
Westerners are allowed TWO 30 day visa exempt entries by land in a calendar year. <- That means you ENTER the country without a visa and get stamped in for free for 30 days.
You entered the country by LAND and you entered WITH a visa in your passport, so no it does NOT count for the two land entries you can get entering without a visa in your passport.
