My understanding is that they are afraid it's not a pesil tekheiles
unless it was made in the order of melakhos given in pereq Cheileq
-- and thus presumably how tekheiles was made for the mishkan.

IOW, they must be gedilim made of pesilos made of tekheiles, and
thus the wool must already be dyed as right after nefitzah.

They have other chumeros, such as raising sheep with an alyah (a flap
of fat hanging down behind the back legs), rather than a modern breed
with hardier wool, so as to satisfy every cheshash that it's tzemer.

Tir'u baTov!
