I think so, Gareth.
To me, Ariel is when a piece has been cut to create an image or pattern, recased and reblown to soften the lines of the resulting bubbles.
This looks more as if the base shape has been indented while still hot, then recased. It wouldn't neccessarily have been a mould used - a tool could be.
I do see the same "ginger jar" shaped piece in your pinterest link as is in the museum link above.
That looks cut, not moulded or otherwise hot shaped.
