If that is your only choice then you did what you could, and pulled over when it was safe. But yes, if you see something coming that you know is going quicker than you you pull in and reduce your speed allowing the faster car to pass, then pull out and continue back up to 100 mph or wherever you were.
It may not be correct in our books, but that is the way it works over there [to an extent].
