When a Thai fighter is fighting a non-Thai and appears relatively dominant, they usually look pretty relaxed. You would think that these Thai fighters would be more aggressive, but when you really watch them, most are relatively calm. They usually aren't even throwing as many shots as you think they are. I'm generalizing of course, but humour me.
Although they aren't hanging back, the Thais usually aren't rushing forward with 5 hit combos either. They tend to throw in shorter combinations, but do so in a manner that dictates the pace. While their opponents try to get off with several techniques in a flurry, the Thai fighters tend to keep calm, and interrupt or stifle the attack. It can be a well timed push kick to a smothering clinch game that helps them keep the fight from getting out of their control.
Whatevever it is, you're seeing experience and tactics in play. It's a game of quality vs quantity. The Thai fighter is usually looking to throw less and therefore slow the opponent's pace down. They do this by being more effective, rather than more active. Sittichai is one of those fighters who seems really active, but really, he's just throwing strong and well place shots.
