I'm unable to reproduce this on current master.  I tried:

0. emacs -Q
1. M-x eshell
2. emacs --help
3. C-c C-p

At the last command, point correctly moved to the previous prompt.

Can you reproduce this on Emacs 27 or 26?  If yes, could you please
provide more details on how to reproduce it?

Perhaps there is something in the output of the particular command you
used that confused Eshell?  That's just a wild guess, though.

Best regards,
