Visiting another world is an entirely different matter compared to seeing it, It's even stated that her power has becomed "the ability to manipulate boundaries". In the end, there are many evidences prove that Maribel is Yukari herself, so that's not so surprise.

"A boundary is the border between two things, such as life and death, or day and night. Taken to its most extreme conclusion, a boundary defines something as otherwise, there would be no difference between anything. Thus anything that exists by definition has a boundary, whether it is a tangible physical object or an intangible esoteric concept."
