Twitter Videos

Hello!
Does anyone know why Inception won't pull some videos posted on Twitter?

Here's an example:
Inception won't pull: https://twitter.com/FS1/status/821147602867482625
But does pull: https://twitter.com/FS1/status/821137646508347392/video/1

Also, does inception pull vine video posted to twitter?

Thank you in advance!
Mildred
