It was that way prior to the timeskip. But considering the extend that Ultears Arc of Time "evolved" maybe Meredy went through a similar power up and can now transfer actual wounds (and by extension healing) between people.

But in that case I think Wendy could only heal wounds through the link that are shared by the people. I doubt that if one has a broken arm and the other a borken leg that Wendy could heal one and fix the other through the link too.
