DAX values calculation confusion

[Anonymous]

Hi

I am a starter for power bi.
I were checking out a blog https://www.sqlbi.com/articles/the-importance-of-star-schemas-in-power-bi/

I really got confused how the values in calculation work!!! I am representing the same scenario provided in the blog. Someone please help me to understand.

VAR NumOfAllVisitsSameSalon =
CALCULATE (
[# Visits],
REMOVEFILTERS ( 'Visits' ),
VALUES ( 'Visits'[Beauty Salon] )
)

My understanding : The calculation is removing the filters in 'visits' table globally and values will take unique values from beauty salon column. So the count is 4 since there are 4 types of beauty salons. But when I pull this measure into the table already present in view it shows 3. Why?

Question 2:

CALCULATE(
[# Visits],
REMOVEFILTERS ( 'Visits'[Beauty Salon] ),
VALUES ( 'Visits'[Group] )
)

My understanding: There is only one filter(slicer) in the view. This same calculation as Remove filter with column name is showing different values for the table in view. But when I use this calculation as remove filter with table name it is showing a common value 5 for all the rows in table view. Why?

What makes difference for remove filter with column from table name even after having only one slicer in view?

Thanks in advance

Based on my test, the removefilter on a table similar to ALL function, 

Slicer won't affect the results of removefilter:
