"Amon is stealing the gift. What a jerk!"

According to Sc2coop-com…
If players capture 2 consecutive gifts, Amon will steal the third. Players cannot stop it.

… If you’re good enough to keep tabs on more than 2 gifts in a row, shouldn’t we be rewarded with, that many gifts? Plus, I don’t believe it works the other way around right? If Amon steals 2 consecutive gifts, he isn’t hit with the same restriction either?

Probably somebody in the mutation department back then thought this mutator is too “rewarding” for players.
As if the gifts spawning far behind enemy lines weren’t enough, right.

What they alternatively could do is make the waves that protect the gifts way larger.
