It's not really a "discrepancy".  It's just that the latter example is a
shortcut for the first.  (Well, it would be a shortcut if you used "201"
instead of "wx.NewId() in the first.)

wxPython has, over the years, developed sensible shortcuts for many common
operations.  The GUI generators tend to use the "long" way, since that
tends to be the original method that will work with any version.

Also note that, in the first example, you are given a wx.MenuItem object to
work with, should you need it.  The second example hides it.  It is rarely
necessary to access a wx.MenuItem directly, so this is not usually an
issue.
