Oddly enough, my pokemon game does this like 15% of the time I try capturing something. This helped me capture Kyurem ;) EDIT: Today it helped me catch an Absol :D

Answer 1

No you didn't, What you have luckily experienced is a Critical Capture.

In Generation V, there is a chance of a critical capture, where the Poké Ball will only shake on the ground once before capture. When a critical capture occurs, the Poké Ball will make a high-pitched whistling sound as it is thrown, then pause in mid-air, and shudder before it drops down to the ground.
