 When neither checked nor unchecked keyword is used (that was 
 unchecked context when compiling this code) bge is used. When using 
 checked or unchecked keywords then clt along with brfalse is used. I 
 don't know whether this is better than bge but this is definitely 
 inconsistent so I think this is a bug.
