Not using the %dist tag doesn't mean the F12 package won't be LZMA compressed.
What matters is when one updates, say from F11 to F12 the packages that don't
have the %dist tag won't be updated (until a new version is available in the
updates repo) if the version and release in both distros is the same: say,
foo-1-1 in F11 and foo-1-1 in F12.

When the dist tag is used the F12 package foo-1-1.fc12 will be "newer" than
foo-1-1.fc11 and thus will replace the old one.

In case the package is (close to) identical in both distros [no binaries
compiled], not using the dist tag saves some download and update time.

Of course, generally speaking something is compiled in every package and the
%dist tag should be used, so from a stylistic point of view using it could be
advised in these cases too. However, if the package is as big as the SRPM (11
MB) I wouldn't put in a %dist tag since nothing is gained from it.
