The recommendation is based on the statement of a Debian Release Manager 
some years ago[1].

Basically it may happen that a particular package is removed from 
unstable, which will also affect other packages that depend on it.

With testing in sources.list the package can be installed from there 
instead.

Because apt[2] by default prefers newer versions of a package, if a 
package is available in unstable and testing with different versions the 
unstable version will be preferred.

So the only downsides I can think of would be slightly longer download 
times on 'apt update' and possibly a late alert that a specific package 
is being removed from Debian (typically packages are removed from 
testing first, but it may happen the other way around as well).

[2] and other package managers like aptitude, etc.

Hope this explains,
Andrei
