That's the exact same solution.  The only difference is rather than 
specifying the ALSA configuration in the, er, ALSA configuration file, 
you're embedding it directly in /one/ application's configuration.  
Therefore, you need to remember that configuration for every application 
for which you want to use that same configuration.  The ALSA 
configuration file simply allows you to assign a human-readable, 
descriptive, and memorable name to that configuration, or--even 
better--to specify which configuration should be used when the 
application doesn't request a specific configuration (i.e. set the default).

You /never/ need an ALSA configuration file.  Those who understand ALSA 
configuration files, though, find they make life easier.  As a matter of 
fact, few configuration files are ever required for any application.  
It's just a matter of whether you want to do things the easy way.

(This is not aimed at you, specifically, but at all the people who don't 
understand ALSA configuration files and keep putting things like, "This 
is not required on Fedora Core 5 and 6 systems," or "If you are using a 
version of ALSA newer than 1.0.12 -- <theoretically authoritative URL> 
states that for most uses an .asoundrc is not necessary," etc. all over 
the wiki pages.)
