Do you have sources on this? I did a quick research and the only thing that I found was this article that argues that Neoliberalism definition changed over time and it would be an anachronism to take how the therm is used today (for example in this post) to define what they mean at the time, and the closest definition for them would be liberals, not neoliberals anymore. Which is totally fine given the time that has passed, and specially how political definitions are hard to define without context (example on how we consider left and right nowadays and 200 years ago for example, its not the same ideas)
