If you're already linking it, how about checking the dates?
Except for 1.16a NONE of them were posted before the actual patch. Check the dates and see for yourself, all of them except 1.16a were posted the day the patch happened.
edit: I'll add the dates just to make it clear:
Patch Notes 1.17a: 25th April
Patch Maintenance 1.17a: 25th April -> delayed to 26th
Patch Notes: 1.17b: 23rd May
Patch Maintenance 1.17c: 23rd May
Patch Notes 1.17c: 15th June
Patch Maintenance 1.17c: 15th June
So...this is actually the 2nd time since the release 11months ago that they released patch notes more than 1 day before the actual patch so yeah, I think my "parallel universe" reference does apply ;)
