Using parameterised expression with outer set expression

[mbn]

I have the following construct

1. set analysis is stored in a variable. This expression is parameterized so i can reuse it across multiple fields

2. the variable is used in a master measure

3. the master measure is used in a viz object and i apply additional filters to it with out set expression

Example:

vVariable: sum({<Date= {'$(MaxDate)'}, $2, $3>} $1)

Measure = $(vVariable(Field1))

Viz object expression: {<Field2 = {a,b,c}>} Measure

The problem is that this construct is not filtering my Measure according to Field2 scope. However, if I add Field2 into the base measure, I get an expected result - e.g., Measure = $(vVariable(Field1, Field2 = {a,b,c}))

Is there a limitation to using parameterised expressions with outer set expressions?
