I wouldn't say I'm an expert in maze generation either, but I would agree that it would be nearly impossible for the following reasons:
1.) The specific maze style used, with the semi-random angled lines within a circle shape, isn't the most mathematically simple form of a maze. If it was a grid pattern in a rectangle, there might be a tiny chance of two people making the same maze, but to create a maze of that style would require more creative programming, with more tune-able parameters, and more decisions left to the implementer.
2.) In order to choose from the vast number of possible mazes that fit a certain pattern, the algorithm is almost certainly going use some random number generation. Even if two people were using the exact same maze algorithm, they would have to also have to use the same randomization process, and start with the same seed in order to arrive at the same maze. I guess it wouldn't be impossible for both people to explicitly choose the same initial seed, (or arrive at it randomly) but that would be very unlikely.
