No, trolling is when you attack someone for bringing up a legitimate question.
The presentation obviously left many with the impression that the button was capacitive and would just wake on resting the finger on it.
If you were clairvoyant enough to realize Apple wouldn't be that progressive, congrats, but it's certainly not trolling because many others felt the same way.
And for the record.... "With just a touch of your home button, the sensor quickly reads and unlocks your phone" ... there's nothing about a press, or a press and hold, or a double tap combination.
Look:

0:53 - into the video, it clearly shows the phone is in sleep\dark.
1:39 - it states that the steel ring acts as a sensor, detecting your finger on the button. Nothing about having to wake the phone prior to it being able to detect that your finger is there. If you have pressed the button, obviously the phone is then awake, so if a fingerprint is required, why would the steel ring need to even be present? It already is awaken by your press of the button, and it automatically prompts for the phone to wake, so that action alone would wake the sensor. Complete redundancy if the steel ring isn't the thing meant to wake the phone.
If you think it's absurd for anyone to misinterpret the communication in the video above, english must not be your primary language.

Also.... if you want a crystal-clear quote....

24:35 - "The (home button) includes the TouchID Sensor. Around it is a stainless steel detection ring, so the sensor knows when to read your fingerprint just by the fact that your finger is on the button. You don't even have to click it."
I'm not sure how any english-speaking human can interpret "You don't have to click it" as having to click it.
I'm interested in how you defend this one.... I thought I'd heard him say that, but I wanted to go back and watch and validate.
My guess, after seeing that, is that they had issues with false activations in pockets or when against the cheek on the phone and disabled the auto-on.
