Tsubasa chronicles and Cardcaptor sakura?

It sounds like you are watching the OVA's of Tsubasa which are 5 episodes long. There are two seasons and five OVA's. The first season follows the manga, the second season follows the manga for a bit and then leaves off from the manga the first three ova's follow off from the manga where the second season diverts and the last two ova's follow the manga but later chapters. The reason the Syaoran goes like he is is are major spoilers and never covered fully in the series or ova's.
