Bad placement...or 'it makes no difference'?

So, Nurofen are currently running an ad campaign across the Rail and Underground network. This was the ad I saw that makes reference to Holborn and Ealing Broadway.

I found the ad on the Northern Line.

This prompted several questions in my mind:

1) Is this bad planning? The Northern Line does not go through Holborn or Ealing Broadway so could they not have run with 2 station names along this route?

2) Does it really matter? Anyone that works in London will have a fairly good idea as to where both locations are. The fact that it is not on the route where the ad is seen probably wouldn't bother them.

Since seeing this ad, I have seen another making reference to Hanger Lane. It was on a South Eastern train. 

What do you think? Does it actually matter?

If they are spending large sums of budget on an Outdoor campaign, should there not be synergy between the creative and the media?
