Counter Doubling on Itself

[Raish]

Is counter supposed to keep doubling its damage if the opponent keeps switching?



Start of turn 2
ALLALA called noscoper420 back!
ALLALA sent out rude'ish! (Snorlax)

Snorlax used Body Slam!
The foe's rude'ish lost 26% of its health!

ALLALA: go not to chansey
ALLALA: and then to chansey

Start of turn 3
Raish called Snorlax back!
Raish sent out Exeggutor!

The foe's rude'ish used Counter!
Exeggutor lost 282 HP! (71% of its health)

Start of turn 4
Raish called Exeggutor back!
Raish sent out Chansey!

The foe's rude'ish used Counter!
Chansey lost 564 HP! (80% of its health)
ALLALA: yeah
Raish: yup
ALLALA: you were right

ALLALA: about doubling

According to Crystal_'s findings, yes that is indeed supposed to happen.

Metalgross found that 

Switching, full paralysis, and using a multi-turn move will not reset the last amount of damage done, allowing Counter to counter itself as well as self-inflicted recoil damage.

SO yeah its legit
