I wouldn't worry about the heatpipe bending slightly, during shipping. That amount of bending + correcting it shouldn't be an issue.
I can't imagine it would bend, once installed. If you hit it hard enough to bend it after mounting, it's probably better the heatpipe absorb that force rather than transmit it down to the motherboard. The swiveling should also help, there.
What slightly bothers me about this is the"swivel" feature. As neat as it is, that seems like it'd hurt the ability of the heat pipe to absorb heat from the SSD. Then again, it does seem like a little bit overkill for the dozen or so Watts a M.2 drive is allowed to burn.
