You can't just pick and choose which runway you want, it's governed by the wind. You take off, fly the SID (standard instrument departure), then you join the airways and go where you need to go. Leeds has a number of SIDs via nearby VORs. For example, POL1W is a 32 SID, and POL1X is a 14; they both terminate at POL VOR, just that X will take a fraction longer as you're initially flying away from the VOR.
Say the aircraft was going to take off on 14 and head in that general direction, they would have taken off into the wind (the general rule), so despite pointing the right way they would have a headwind. Taking off on 32 into a headwind would mean they actually had a tailwind once they got to POL and did a U-turn. Clear as mud?
