AND filter or Slicer visual

Hi, woony 

The method in Greg_Deckler 's blog seems amazing and that seems to work, but for me as you said, the DAX part is hard to understand and I still don't understand why it works. I need to take time to figure it out.

I try to solve the problem myself and here is my solution.
to create a measure to get the Name:

_NAME = 

VAR _Module_ID=SUMMARIZE(ALLSELECTED('Modules'),[module_ID])

var _Install_ID=SUMMARIZE(FILTER(ALL(Facts),'Facts'[InstallID]=MAX('Facts'[InstallID])),[ModuleID])

var _except=EXCEPT(_Module_ID,_Install_ID)

var _count_NOT_ID=COUNTROWS(_except)
var _theID=IF(_count_NOT_ID=BLANK(),0,_count_NOT_ID)

var _if=IF(_theID=0,
CALCULATE(MAX('Installs'[InstallName]),FILTER(ALL('Installs'),'Installs'[InstallID]=MAX('Facts'[InstallID]))))

return _if

Count_Name = 
var _t=SUMMARIZE(ADDCOLUMNS('Facts',"_name",[_NAME]),[_name])

return COUNTAX(_t,[_name])

Result:

Please refer to the attachment below for details. Hope this helps.
