I see from two facts that it is in the wrong position:
1) I need to press C-p to go to the position *before* the undo. From
this I see that point after undo is at least one line off.
2) C-x = immediately after undo confirms this, saying:
point=323 of 322 (EOB) column=0
While point before undo is point 281 of 322.

Please see #21722. It shows that point position after undo is different
from what it was before, just as in this case. I constructed the case
shown in #21722 due to the issues with undo after process output, and I
suspect these issues are related. Redisplay may also be involved.

The font and even window size definitely have an impact on this
issue. Please try a different window size, and I hope you can then
reproduce the issue, or at least #21722.
Thank you and all the best!
