Carbaryl AI label: does this protect bees?

Thursday evening, 5/30/2013, my partner and I attended a presentation provided by CSU Extension about native pollinators.  There was a slide handout to accompany the presentation.  I was particularly interested in the slide labeled:
 
MOST EXTENSIVE BEE LANGUAGE WARNING ON A LABEL!
 
This slide was for a product called Carbaryl AI, which I had never heard of.
Active Ingredient:
Carbaryl (1-naphthyl N-methylcarbamate) ... 43% by wt.
Inert Ingredients:  ... 57% by wt.
 
The slide said; this is a quote:
ENVIRONMENTAL HAZARDS
BEE CAUTION:  MAY KILL HONEYBEES AND OTHER BEES IN SUBSTANTIAL NUMBERS.
This product is highly toxic to bees exposed to direct treatment or residues on crops or weeds in bloom.
For crops in bloom, do not apply this product to target crops or weeds in bloom.  Notifying beekeepers within 1 mile of treatment area at least 48 hours before product is applied will allow them to take additional steps to protect their bees.  Limiting application to times when bees are least active, e.g. within 2 hours of [unreadable word here] or sunset, will minimize risk to bees.
 
I was horrified to learn that should I be notified of a pending application of this poison, I had 48 hours to protect my bees at my initiative.
 
Tonight, I'm doing a little research, so I looked up Carbaryl AI and found the actual label.  It reads differently.

This is a copy and paste:
ACTIVE INGREDIENT:
Carbaryl
(1-naphthyl N-methylcarbamate) ........................... 43.0% by wt.
INERT INGREDIENTS:
.............................................. 57.0% by wt.

TOTAL ............................................ 100.0% by wt.

ENVIRONMENTAL HAZARDS
This product is extremely toxic to aquatic and estuarine inver-
tebrates. For terrestrial uses, do not apply directly to water, or
to areas where surface water is present or to intertidal areas
below the mean high water mark. Do not apply when weather
conditions favor drift from area treated. Do not contaminate
water by cleaning equipment or disposal of wastes. Do not
contaminate water when disposing of equipment washwaters.

next page:

This product is highly toxic to bees exposed to direct treat-
ment or residues on blooming crops or weeds. Do not apply
this product or allow it to drift to blooming crops or weeds if
bees are visiting the treatment area. Contact your Cooperative
Agricultural Extension Service or your local Bayer Environmental
Science representative for further information.
 

To me, the text is different in some pretty important ways.

The first does not mention water, the second emphasizes water.  The first claims that protecting my bees is my responsibility, the second states it is the applicator's responsibility.

Mention of water may have been intentionally left out by the producer of the slide which was intended to be discussing native pollinators.  No problem. 

The responsibility piece is a huge issue.

We beekeepers put a great deal of faith in "The label is the law."

Questions spring to mind:
Which is correct?
I can't find a date on the either version.
The second version is EPA Reg. No. 432-1227
The first version is EPA Reg. No. 432-1227-72112

Could it be that, unknown to us, the label law has changed?
The CSU Extension Service is now teaching this to farmers.   Is it correct?  If not, why is it being taught?  If correct, exactly when and how did the label law change?
