Flying through Space and Time

[Gronzak 3]

when you use the crystal in the Rose theater and get to rute 4 you can use fly, not to go anywhere in the past, but to any location in the future (or present?)
idk if that happends directly when you use a pokemon with fly, but at least happends with the Golden Wings.
Only in rute 4, tho, not kugearen or the shifting cave.
This is how it looks:

Spoiler

you can still use pg up / pg down to change region and fly, for example, to west gearen

I guess because the devs did not want to reveal the map of the past?

Does route 2 in the past work? Because then it might be because route 4 is an actual route in the future
