No, it wasn't. The Doctor had no idea how long the ship had until crash, and he was determined to convince Cass to get into the TARDIS - he wanted to save her, and bare in mind this Doctor has suffered more emotional loss pre-Time War than any other Classic incarnation. It's possible that he just about to retreat into the TARDIS when the ship actually crashed and just got the timing wrong.
And the Sisterhood was pretty well explained in the minisode. How much detail do you need from "cult that knows the secrets of regeneration" to understand it.
The TV Movie? Half-human on his mother's side? Master as a snake? The Doctor not checking the scanner to see where he is, but instead walks into an ongoing gunfight? Even the Eleventh, the clumsiest incarnation, takes better care than that! WHERE'S THE SENSE THERE?
