I wouldn't be sure it's temporary. I think there's some exceptions to the concrete ties requirements for switches. It's quite common to use wooden ties for switches because they can be drilled where necessary, whereas concrete ties need to be manufactured with the correct mounting points. For a switch every single tie need to be different, so the manufacturing would be difficult.
Personal speculation though, it's possible it's temporary.
