When i run the command only the buffer that happened to have the cursor in it (the active buffer?) is positioned at the end of the file. All of them are reloaded though. What I expected to happen is all files to be refreshed with all buffers showing the last couple of lines of each file.

OK, so you *don't* have the buffers open in the same window, switching between them with buffer commands like ":b" or ":bprev" or ":bnext". You have several buffers open in multiple split windows.

The ":bufdo" command works by cycling through all the buffers open in Vim, loading them one by one in the current window. It does not affect the other split windows.

At the moment you visit any given buffer, it is now open in *two* windows: the currently active window, and the window you already had it open in. You reload the buffer, which affects both windows, because both windows are different views on the *same* buffer. Then you jump to the end of the buffer. This only affects the cursor position in the *current* window. The existing window is not affected. Then, you move on to the next buffer, so it appears that only the reload happened.

As Bram suggests, you probably actually wanted to use ":windo" instead of ":bufdo".
