The writer is correct, and the point should be made even more clear.
They are using the word "isolate" out of context.
They are using it to mean that a sample of SOMETHING was taken from one particular individual, and is therefore "isolated" from any other individuals' SOMETHING.
That is NOT what "isolate and purify" means in the scientific, Koch's Postulates sense.
To "isolate and purify" means to isolate A PARTICULAR MOLECULE OF A PARTICULAR THING out of the SOMETHING that was taken in the sample.
You could take a blood draw from someone, and that blood sample might have hundreds of things in it. Out of all those things ("SOMETHING") you need to ISOLATE THAT ONE PARTICULAR THING that you think should be studied (such as a SARS virus, COVID whatever, etc.
You then purify to make sure there is NOTHING ELSE OTHER THAN that one particular thing. Only then, can you say the substance has been "isolated and purified."
They have NEVER done this with Covid-19 or SARS-Cov-2 (or HIV, for that matter).
Which means ... they are blowing smoke up your backside when they claim they "isolated" it from a particular patient.

THAT means nothing at all.
