create new table using a measure as a filter

I have two tables Table 1 and Table2 which are unrelated, and by using a measure which I build up from a selection of values from Table1, I want to build a 3rd table which is a subset, ie a filter, of Table2.

Here's the measure I create from Table1. (you can ignore the hardcoded result R2 for now)

Selected name = 
VAR R1 = SELECTEDVALUE(Table1[Column1])
VAR R2 = "Rashi"
RETURN
    R1

Then I create Table3 from Table2

Table3 = FILTER(Table2, Table2[Name] = Table1[Selected name])

This results in Table3 with zero rows.  

However, if I change my measure to use the hardcoded result, eg

Selected name = 
VAR R1 = SELECTEDVALUE(Table1[Column1])
VAR R2 = "Rashi"
RETURN
    R2

then Table3 is created with a single row, which is what I want.  

How do I go about creating the table using the variable R1 in the measure, what is the difference between returning the values R1 and R2 - I've done some tests and can see no difference.  An example PBI file is attached here.  

Thanks in advance.
