[Q] Is this true and does it mean there is dynamic defragmentation in ext2/3?

Someone recently posted the following statement midway down the page 

>You don't need to defragment ext2/ext3 because as you use the 
>filesystem file blocks and inodes are moved around and reallocated 
>to keep the data nearly contiguous. It's not perfect, but it works 
>fairly well and you should almost never see a performance 
>degradation caused by the filesystem's fragmentation.

Is this statement accurate and does it mean ext2/3 is performing a 
sort of dynamic defragmentation?
