Makes perfect sense to me.

The older one is NOT flat fielded.  Neither are standard loupes. As they are
not "corrected" to flat-fieldedness, you can actually use them off-angle.

The newer one may also be a telecentric design which also alters off-angle
viewing.

When viewed at a direct angle, both should look almost identical.
