LCSH "alternate labels"?

Would be grateful for an explanation of the use/ significance of
"alternate labels", as here for example:

http://id.loc.gov/authorities/sh85035979

Can we use the alternate label in a 650 if we prefer the term? If not,
how would it be used?

Thank you,

Cab Vinton, Director
