Maintenance windows applies only to task sequences doesn't work

Question

Problem:
SCCM 2012 R2 CU4
Task sequence deployment run outside maintenance windows when the maintenance windows is set to apply only to task sequences.
When the maintenance windows is set to apply to All deployments, the task sequence deployment run inside maintenance windows as expected.
The maintenance task defined was as:
Name: Maintenance Windows of Collection Coll_A
Time: 10:30am to 06:00am
Date: 20th March 2015
Apply this schedule to: Task Sequences
The task sequence defined was as:
Deployed to Collection Coll_A
Time: Run as soon as possible
The task sequence run at 9:48am on a workstation that is member of Coll_A.
There aren't other maintenances windows on others collections.

Answer 1

When was the client added to the collection? Was it able to retrieve those MW policies before it received the TS?

1_the client was added at the 9:30am.
2_Yes it is.
I have done another test and the result is the same:
_ first setting up the maintenance windows in Coll_A,
_ then insert the client in Coll_A and force a machine policy evaluation
_then deploy the task sequence in collection Coll_A
