He's running at a high fraction of c; high enough that the Lorentz factor is 2. So he sees everything in his path of travel squished by a factor of 2 along his axis of travel.

So when he reaches it, the end of his pole reaches the back wall at the same moment he's in the doorway. His pole knocks out the back wall, and he's where it was as the back end of his pole reaches the doorway; the front end of the pole is now five feet past the former back wall of the shed.

The critical bit is that all of this ONLY applies within the universe it’s happening in; jump occurs outside of it.

Jeffrey’s example of the 300km spool of fiber is instructive here, by analogy.

Jump is a shortcut bypassing the normal space ‘spool'; at no time is anything going faster than light*. Yes one pulse arrives much sooner than the other , but that’s because one pulse travelled 10 cm, the other 300km.

If the ship itself is moving at a significant fraction of C observers might be able to see the kinds of things you’re talking about, but it’s NOT because the ship has moved through jump.

Einstein-Rosen bridges are consistent with the equations of relativity; the question is can they exist? How do we make them? can information travel through them?

*even the light isn’t going C, since it’s traveling through a non-vaccuum…a pulse sent through 300KM of fiber optic will arrive significantly AFTER a pulse sent through 300km of vacuum, by quite a bit; a cursory google search brings up a figure of .31 c through a typical cable.
