Possible. I just futzed around with the export settings (needs some work) and I could see that. One thing I did notice was I could not simply set that setting in existing preset; it kept reverting. Tried creating a new preset and same behavior. I ended up killing both of my created presets, creating one anew [happened to have "Set viewBox" enabled] and then saved and all is perfect now. My gut tells me it worked because the base preset had it enabled already and that is why the others wouldn't retain their settings.
No matter what, you helped me solve an issue that was bugging me for a while as well as other Origin/AD users. I already filed RFE for them to update their doc and will go forth and share with their community. Cheers!
