You are right!
Therefore I read the chapter in my latex book and now everything is
clear! ;-)
In multiline format (eqnarray) the left and the right part are real
formulas,
but the middle part is a textformula! So it's not possible to write
a sum super/subscript under /above the sum-symbol. If you choose the
array-format, all parts are in textmode.
You can type the sum in all three parts of a multiline formula and you
will
see, that the middle sum is typed with super/subscript shifted to the
right,
the left and right one the one with super/subscript above/under the sum.
The option \limits works only for integrals, in both math modes!
Therefore it's not correct, when LyX views these symbols different to
the latex-convention.
hope this helps
Herbert
