US Secretary of State Mike Pompeo is now in the Saudi capital Riyadh as he tours the Middle East to reassure US allies in the region.
A spokesman for the coalition said it "has begun the process of our deliberate withdrawal from Syria". The confusion was precipitated by President Trump's shock announcement over the issue last month.
The pullout was reportedly sparked after a phone conversation between Trump and Turkish President Recep Tayyip Erdogan.
Turkey on Saturday welcomed the latest statement made by Washington's top diplomat over Ankara's right to defend itself from "terrorists" after the US withdraws from Syria.
"We also know that those fighting alongside us for all this time deserve to be protected as well", he added.
"We have achieved the goal that we set out to achieve", he said.
Why is the USA withdrawing from Syria?
Turkey considers the YPG a terrorist movement and has repeatedly threatened to move into Syria to create a buffer zone along the border.
Trump's National Security Adviser John Bolton had a tense meeting with Turkish officials in Ankara this week.

No U.S. personnel have left Syria yet, according to a Pentagon spokesman. Also, U.S. troops are among 200 to 300 coalition troops at a garrison in southern Syria known as al-Tanf, where they train and accompany local Syrian opposition forces on patrols to counter the IS group.
The woman was reportedly sent to Syria where she took medical training from French and USA doctors for six months and was later transferred to the hospitals in the region for practice, she said in the testimony.
Representatives of the Syrian Democratic Forces, a military coalition dominated by Kurdish fighters, declined to comment Friday, suggesting instead that the USA military should explain its plans. "We will be like second-class citizens at best, if we survive as Syriac Christians and Kurds".
Mr Pompeo said yesterday that the speech had not taken aim at individuals but rather the ideas of the previous administration, adding that the Obama-era policies opened the way for Islamic State and the spread of Iran's influence in the region.
But Bolton also said the United States was still seeking some guarantees of that agreement through "protocols and procedures".
The U.S. -led coalition in Syria is beginning to withdraw troops from the country.
There are 2,000 US troops in Syria and while the military has orders to follow the president's decision to withdraw, they have no timelines attached for how long it will take. Trump's decision drew intense criticism that the USA was abandoning its local Kurdish allies and led to the resignation of Defense Secretary James Mattis and Brett McGurk, the special presidential envoy for the global coalition to counter ISIS.
