My only angle to understand would be that it gives us ‘first dibs’ in the summer, almost like we have for TGH, and we don’t need to ‘move money forward’ as BT & JL keep referring too whenever asked. I.e we want to sign him but not for that fee now, but do in summer, so basically make his initial stay a loan before making it perm in summer rather than run a risk of losing out to someone else going in fresh from summer.
All 2+2 on my part though.
