typescript question

There is something I don't understand about the typescript business 
(using ConText version june 30, 2004):

By calling \setupbodyfont[lbr] the following script (referred to als 
typescript number-1) in type-buy.tex (lines 161-170) is executed:

\starttypescript [lbr]
	\usetypescript [serif,sans,mono,math,calligraphy,handwriting] [lucida] 
  [name,special,\defaultencoding]
	\usetypescript [serif,sans,mono,math,calligraphy,handwriting] 
[default] [size]
	\usemathcollection[lbr]
	\usetypescript [all] [lucida] [\defaultencoding]
\stoptypescript

Also I have defined somewhere else a typescript (number-2):

\starttypescript [Times]
	...
\stoptypescript

WITHOUT the line "...[all]..." in typescript number-1 all goes well, 
lucida fonts result in the product.

However, WITH the line "...[all]..." in typescript number-1 there is 
found the following match, as can be seen in the log (by setting 
\tracetypescriptstrue):

 >>> fonts : enter [Times] [] []
 >>> fonts : check [all] [lucida] [texnansi]
 >>> fonts : matched

Now that seems strange to me. I might be misunderstanding the 
typescript search mechanism, but why does it turn out that the search 
key [lucida] is ignored? Here it seems that after the [all] the 
following search keys are ignored, reducing the check to [all][][]; but 
why then bother giving these 2nd and 3rd key at all? But even if this 
behaviour is implied by giving the first search key as [all], it leads 
to wrong results. Because now the typescript number-2 is executed too, 
working havoc to the font setup.

Is there someone who can enlighten me on these matters? Thanks in 
advance.
