Completely a side effect of that, yes. The way copters used to work was a bug caused by a mistyped less than or greater than sign (don't remember which, offhand), but when I tried replacing that with the way they were intended to work, it still wasn't especially fun. So instead I made copters not overriding your xSpeed at all, which naturally had the side effect of them not override your xSpeed in the specific case of your being in a sucker tube. We didn't think of any other levels where this could be a problem, though, and it should still be possible to get the powerup by warp or bouncers.
