It is a reasonable enough question.  The OP obviously had already read
the man pages, which seems to describe the same cababilities for 
lvresize and lvextend/lvreduce.  He wants to know why we have both?
Is it historical accident?  Or is there some subtle feature that
distinguishes the two?

First of all, notice that all three commands are links to the lvm
command, so they share code.  As far as I know, they are all just
alternate syntax for the same operations.  You might want to 
use lvextend rather that lvresize, for instance, to avoid accidentally
reducing instead with a typo and destroying data.
