Because it is still classed as ticket touting!!! What you are saying is semantics, it is still exactly the same!!!
If you offer it to the guy for £30 and he says yes. Then he is clearly happy. There is NO difference in what you are saying.
Little blurb explaining it all a bit further.....
Touts will often try to sell tickets outside football grounds at  inflated prices. However, resale of football tickets is illegal under  section 166 Criminal Justice and Public Order Act 1994. This Act  stipulates that it is an offence for an unauthorised person to sell a  ticket for a designated football match or otherwise dispose of such a  ticket to another person.
  However, touts began to find ways  around this legislation, for example, by selling other types of  merchandise at an inflated price with the inclusion of a ‘free’ match  ticket. Consequently, this Act has been amended by section 53 of the  Violent Crime Reduction Act 2006. This imposes the following  restrictions in relation to the resale of football tickets:
  
- newspapers cannot carry advertising for ticket touts;
 
- touts are prevented from claiming that a match ticket comes ‘free’ with another product;
 
- section 166 will apply to people offering tickets with a wider/hospitality package and people who provide tickets to touts.
 
  If  someone is convicted of ticket touting at football matches under UK  law, they may be liable to a fine of up to £5,000 and have a football  banning order imposed upon them.
