I think what Piskor has in mind is that the originator of an action and its results seem to exist in slightly different time-frames in the same panel: for example, Andy is at the end of the follow-through of a throw, and the thing he's thrown is already shattering a faraway window.
To be precise, this isn't just a matter of causes being visible alongside their effects, but being visible in different temporal frames of reference within the same panel. It's as if the motion line were a sort of time-distortion device, guiding the reader from a slightly-past "present" to a somewhat-more-present "present," all within the panel.
In order to add my own two cents to the discussion, here's my favorite example of this weird feature of the way comics represent time:

Go on and click to enlarge it. Take the time to read it. That's a splash panel from Mister Miracle #15 (Sept. 1973), written and drawn by Jack Kirby.
What's going on in that panel? I detect at least three, and maybe four, temporal frames of reference swirling around each other there.

Okay, some stuff happens before the panel actually begins. This includes everything leading up to ...

(A.) the tossing of a grenade.

Shilo (B1.) sees the grenade, (B2.) calls out a warning, and (maybe not simultaneously—so B3? or C?) trips Mr. Miracle.

(C? D?) Mr. Miracle falls to the ground.
Of course it's weird that all these different causes and effects are visible simultaneously. I think it's extra-weird that they don't simply "read" from right to left, but follow the actions around the page counter-clockwise from twelve o'clock, like so.

I can't tell whether this panel is a muddled mess or a masterpiece of compression and efficiency. I've looked at this comic so many times since I was a tot that I can't imagine what it would be like to read it without already having read it.

What do you think? Does this panel work to convey its complicated chain of cause-and-effect clearly, or is it confusing?
