unfortunately not true. The attack animation and travel time of the projectile are so long that snip comes through.
Lurkers on the other side can interrupt snip if they are in burrow.
I also noticed during the test that the lurker range/size changes. Ghost snip unburrow Lurker → Lurker burrow → Snip interrupts.
you would expect Lurker to attack Ghost. Ghost is out of lurker range and lurker is out of snip range.
With scan snip just happens. Lurker should always burrow before Ghost starts snip.
infestor are only supposed to support in first line. Infestor are sometimes clunky due to their size and block themselves and other units.
