It is strange that she missed the Oct 5 test, as basically September ended the season until late February, but maybe that's the way drug cycles work.
It's actually quite common for testers to do out-of-competition right after an in-competition tests, on the theory that the athletes think the "coast is clear" and they can start the off-peak regime again.
This was a whole issue with the recent CAS case of the Croatian water polo guy (who was found guilty of test evasion). He was tested at 8pm the previous night after a match in a different town, but couldn't pee quick enough and so had to "get his own ride" back to his home, and then the tester showed up at 6am the next morning. I guess he doped later that night after the in-competition test and didn't expect this, as he vanished inside and later tried to claim the tester met not him, but his brother-in-law (who is 5'6" instead of a basketball-esque 6'6").
Another randomizer is have back-to-back out-of-competition tests. Not fun for athletes, but hey, that's the way it is nowadays.
