Nah. He is also known for instant turns, when he thinks he has bargained enough or when it happens to suit the image he wants to present.

For example say he decided "Vilnius is the moment I stop bargaining, but only at last minute. Lets see what concessions I can get out of them until then" or so on.

It is exactly on brand for Erdogan to suddenly turn his position and go "what problem, there is no problem. What I said last week there was a problem... no no no, I Erdogan The First have solved problem quickly in only few days. Yes we made a deal, I negotiated amazing deal, deal solves the problem. There is No problem anumore. It's solved."

What happened to solve the problem? Nothing, Erdogan just stopped insisting there was a problem in first place and well some flowery language on top to make it look like it was deal to end the problem and not a climb down to end the problem.
