I'm not exactly which case you are asking about but you can do any of 
the following and there may be other possibilities (there are also 
other examples at MetaWikiPedia:Help:Template):

case 1.

article  = "blah",  wikitext = "{{blah1}}"
template = "blah1", wikitext = "blah {{blah2}}"
template = "blah2", wikitext = "blah blah"

article blah displays text: "blah blah blah"


case 2.

article  = "blah",  wikitext = "{{blah1|blah2}}
template = "blah1", wikitext = "blah {{{{{1}}}}}
template = "blah2", wikitext = "blah blah"

article blah displays text: "blah blah blah"


case 3.

article  = "blah",  wikitext = "blah {{blah1|blah|blah2}}"
template = "blah1", wikitext = "{{{1}}} {{{{{2}}}|{{{1}}}}}"
template = "blah2", wikitext = "{{{1}}}"

article blah displays text: "blah blah blah"


I'm not sure how deep you can nest templates but it seems you can go at 
least 3-4 deep.
