The reserve system works like this: -
When on main tank, the fuel goes down the pipe in the picture below, top arrow, some 4" above the bottom of the tank. Any crud or bits in your tank can wash about in the bottom of your tank in the two gallons or so of unused fuel, keeping it away from your carbs.
If you run out of fuel you pull the cable and then the fuel goes through that filter and exits the tank from a small well at the bottom of the tank (Bottom arrow) - which could be full of all sorts of muck, in a 50 year old car.
So, although there is a filter it can reduce the fuel available and cause supply issues.
My fuel injection system needs a 1/2" hose so I have had to modify that filter and take fuel from the bottom, and yes it has caused me some problems.
Saying that, if you tank is super clean, you shouldn't get any problems. IMO that is
