Its returning the actual matched class object. Not a symbol.

Hello
In the laser game tutorial by Stephan B Wessels I was intrerested by this
code:
directionFor: aSymbol
^ self subclasses
detect: [:cls | cls directionSymbol = aSymbol]
The code appears here at the bottom of the page:
http://squeak.preeminent.org/tut2007/html/038.html
What I read this code as doing, in this example is: return an symbol object
which is a sublass instance varable, if it is the same as aSymbol.
What would happen if more than one subclass object had a match?
Also how else can subclasses detect: be used? It looks very interesting.
