Yes, this is how X behaves when your virtual resolution != real resolution.
Chenging the order of the specified modelines, or specifying the modeline
you want (if it isn't specified and you are using a built in default)
will alter this behaviour, as will setting the 'Virtual' config option,

It's a laptop - an LCD screen actually has only one resolution - each pixel
is actually represented by a single dot-element-thingy (technical term :)
on the display, unlike a CRT, where you typically have a much higher density
of phosphor dots than you do of pixels. Thus, laptops have a hardwired max
resolution, and can only really display smaller ones by using a smaller
portion of their screen - some laptops get around this by having special
hardware that 'smears' the display out when the logical pixel display
boundaries don't match the physical ones, but as you note, this results in

Probably a mode your hardware can't actually cope with. Remove it.
