I can help with the basic idea: most colons require a following
statement, either on the same line (one statement) or on all the
following lines indented more than the line with the colon.  (We're only
concerned with the latter case, which Python calls a suite.)

"pass" is a no-op used in such a context where no (real) statement is
desired.  Therefore, it makes sense for an Emacs Python mode to notice a
"pass" (along with certain other choices like "return") and presume that
the user wants it to end the suite -- that is, to use one fewer level of
indentation on the next line.  (Sometimes the user wants even less
indentation, so they type p a s s C-j DEL or so.)

The bug (if it exists) is that newline/newline-and-indent/whatever are
not implementing this behavior properly, resulting in blocks that the
user "obviously" means to be siblings being nested instead (when no DEL
is used).
