The study you linked is from 2015. There have been major advances in the study of DNA in the last 8+ years, IMO.No it does not. Please see the study I linked above where pairs people were asked to shake hands and then one person of each pair was asked to handle a knife with the hand they shook hands with.
"In 85 percent of the cases, DNA from the person who did not directly touch the knife was transferred in sufficient quantity to produce a profile. In one-fifth of the samples, that person was identified as the main or only contributor of DNA to the potential weapon, despite never having touched it."
This is why touch DNA alone cannot be trusted in this or any other case. Touch DNA is becoming more and more controversial because too many innocent people have been convicted based on touch DNA, not just in the USA but overseas as well and I believe in the not so distant future, there will be new rules in courtrooms on touch DNA evidence which may require that touch DNA only be considered IF there is other evidence which proves the suspect was actually in the location.
