She means that lower-case(.) returns a string, not a node-set. It is not possible to continue the 
path with / if the previous steps didn't result in a node-set.

So this can be done:

    keyword/key('nodes-by-keyword', .)/substring-before(., '-')

..as key() returns a node-set.

But this cannot be done:

    keyword/lower-case(.)/substring-before(., '-')

..as lower-case() returns a string.


(Unless you can make lower-case return Text Nodes instead of Strings, I guess..)
