I would not see this as a bug. The behaviour of Forth is 
deterministic: it will execute the first word in the vocabulary 
with that name, that is the last you defined with that name. 
With this feature, you can incrementally expand your definitions:

which is equivalent of course of

I use this sometimes when interactively building up talking to 
hardware.

I'm not a standards boy, so I wouldn't know, if this is 
considered a bug.
