yes & actually i said that. its is the absolute bane of existence on vintage bikes with disc brakes. it will displace fluid back into the res when the lever is pulled. (it fills behind the main seal when the lever is released). if its clogged it will just build pressure behind it and it drags. I've seen it bad enough where it caused a crash, a 75 S3 right into a guardrail on the cherahola skyway about a decade ago. Luckily Bill was ok and .. well, frankly, he is/was used to crashing so he did ok.
Interesting observation. When the compensation hole on my bike became clogged it caused a mushy feeling at the lever, exactly like air in the line would cause. I rebuilt the master cylinder, and bled the brakes twice, but this did not correct the mushy feeling at the lever. Cleaning this hole cured my brake issue completely.
