I guess this is partly a question of personal taste. 

In general I'd prefer to always pass things through explicitly defined parameters. This better documents what parameters a template depends on. 

However in this case I was working on an existing example and I wanted to change as little as necessary on the original code. 

With explicit parameters I need to add a parameter to "hello" and pass the pattern, either explicitly:

greet(pattern)::=<<
<hello("Bob",pattern)>
<hello("John",pattern)>
<hello("Kate",pattern)>
<hello("Barbara",pattern)>
>>

hello(name,pattern)::=<<
Hello, <pattern>
>>

or using the "…" passthru (This requires we also pass the name "by name")

greet(pattern)::=<<
<hello(name="Bob",...)>
<hello(name="John",...)>
<hello(name="Kate",...)>
<hello(name="Barbara",…)>
>>

hello(name,pattern)::=<<
Hello, <pattern>
>>
