Thanks Wendell for your complete explanation. While reading your help, I tested another alternative:

ROW[. = key('relacion_x_cobertura', REL_ID)[1]]

and it worked too.
I think that case is equivalent to generate-id method since all ROW's has at least 1 field different, making the whole ROW different. Is that true?

"Equivalent"? It happens to work because the content is different, but your string comparisons will probably be much longer looking at content than looking at generated identifiers.

Using generated identifiers will work regardless of the content.
