I have given a 'medium' level of confidence as I don't have the full context, but it seems to me that they are speaking in general terms.

Here's a useful article explaining both terms, experience map and journey map:

"A customer journey map is the right tool if you know where you want to focus. For example, we worked with an east coast hospital to better understand its radiology experience. By focusing on one specific journey (scheduling through receiving advanced imaging), we were able to give very specific feedback on where their patients were getting frustrated today, and where to target to build better patient outcomes and loyalty. But it was almost no help to other departments in the hospital.

An experience map is best if you don’t know exactly where the problem is. A non-profit client knew that friction occurred somewhere in their multi-year experience that led members to become less engaged, but didn’t know exactly where. Zeroing in on only one journey within that relationship would have caused us to miss members’ most critical needs. The trade off is that while we had very actionable results that led to them to rethink everything from how they’re structured to their membership approach, we now need to zero in to get more specific on the member experience within specific journeys."
