Subview bounds resizing when frame resizes

I have a custom view with a custom subview. I can't seem t make the 
bounds of the subview stick. When the view changes the subview's 
frame, I want the subview's bounds to stay exactly as I set them the 
first time. The whole point of having this subview is to have a 
separate coordinate system.

I create the subview like this:

   // Add page into our view
   pageView = [[BTPPPageView alloc] initWithFrame:[self pageFrame]];
   [pageView 
setBounds:NSMakeRect(0,0,pageBoundsSize.width,pageBoundsSize.height)];
   [self addSubview:pageView];

and I reposition the subview's frame when the view's frame changes:

[pageView setFrame:[self pageFrame]];

The subview bounds are set correctly at the start, but if I make the 
subview's frame larger, the bounds are scaled larger too. I thought 
from this in the NSView docs that the subview's bounds would stay fixed:

If your view does not use a custom bounds rectangle, this method also 
sets your view bounds to match the size of the new frame. You specify 
a custom bounds rectangle by calling setBounds:, setBoundsOrigin:, 
setBoundsRotation:, or setBoundsSize:explicitly. Once set, NSView 
creates an internal transform to convert from frame coordinates to 
bounds coordinates.

I am using setBounds, so why is it not preventing the scaling? My view 
has the Autoresizes subviews flag off. The view is created in IB, the 
subview in code, as above.
