I just created two very small test packages... that conflict... and I
do not see yum redownloading anything after recieving the conflict
error.
yum install barapp foolib

let me point out to you that what you just saw downloaded were the HEADERS
as found in /var/cache/yum/<reponame>/headers
In my test package case /var/cache/yum/local/headers:
-rw-r--r-- 1 root root 1716 Sep 10 16:58 barapp-0.1-2.i386.hdr
-rw-r--r-- 1 root root 1600 Sep 10 16:59 foolib-0.2-1.i386.hdr
/var/cache/yum/local/packages:
is empty
No packages are downloaded if a detected conflict causes yum to error out.
Now I go back and just install foolib by itself
yum install foolib

Complete!
That download was the download of the actual package. The headers were
NOT re-downloaded!
after this second attempt to install foolib without the conflicting
barapp package,
I now have a cached package.
/var/cache/yum/local/packages:
-rw-r--r-- 1 root root 1987 Sep 10 16:59 foolib-0.2-1.i386.rpm
to recap.....
if yum errors out due to a conflict NO PACKAGES WERE DOWNLOADED.
yum downloads headers from the packages during depresolution.
Packages are only downloaded if depresolution clears successfully.
you are NOT seeing redownloading of anything.
The cache IS working, the header files in the cache ARE being reused.
