Does "more recently" just mean "recently" here?

Here’s the context:

“In England’s residential nurseries in the 1960s, there was a reasonable number of caregivers, and the children were materially well provided for. Their IQs, though lower than those of children in families, were well within the average range, up in the 90s,” Zeanah told me. “More recently, the caregiver-child ratio in Greek orphanages was not as good, nor were they as materially well equipped.

Usually "more recently" implies a comparison between two recent events but here we are talking about something that happened more than half a century ago so I wonder if "more recently" just means "recently here. Thanks!
