Gerry Tosh is a brand ambassador. Whilst I do not mean to sound disparaging, bear in mind that most brand managers are strategically taught how to present the distillery's whisky, perhaps sometimes in ways that do not best reflect the whisky or accepted industry practice.
(For example, brand ambassadors for Johnnie Walker Green are telling us it must be drunk with ice; brand ambassadors for JW Gold and/or Blue are telling us to drink it frozen. Both techniques
reduce the flavour of the whisky, so how much credit do you give these guys?

)
Richard Patterson, on the other hand, is a Master Blender, and
relies chiefly on his nose to assess whiskies and to create his blends and vattings. He certainly recommends swirling the glass.
Which of the two do you think is the more authoratative voice?
Cheers,
