The standards didn't make it clear what it means by crossing multiple Temporal zones, I asked this on the QnA but no one answered
1. Zeno's timeline erasure had already been accepted as speed as it clearly showed the attack travelling, it being hax doesn't stop it from having attack speed, his profile already scales his timeline bust to his attack speed, not to mention that even without using the timeline bust feat, we are told by Whis that he can erase the entire world, furthermore UES verses allow
it to
scale just fine. Also Zeno's timeline bust is treated as a ki blast with EE properties
2. Not sure how this relates to his timeline bust at all, his EE erased a 5d construct and was shown travelling, even beyond said construct to another 5d one, he has also shown the ability to use a specific delete version, just like how GoDs can fire their hakai as blasts or just delete something without anything travelling, timeline bust and multiple statements bump him to 5d EE, so he's not losing that as long as the timeline is 5d. How does something lose EE because it has attack speed?, GoD Toppo's hakai also travels, does he lose his EE too?
That's exactly what it means, unless anyone somehow proves that he doesn't have kibfir whatever reason
