I can't say for sure why it's different, but since there's considerable regional variation in Thai customs, it may simply mean that the monks come from some place with whose customs I'm unacquainted. I only really know how things are done in Bangkok and in the North.
Does it mean that we can't use the bedroom as a bedroom?
I wouldn't have thought so. I mean house-blessings aren't normally carried out with the aim of turning any part of one's home into an exclusion zone.

Dhātūnaṃ suññaṭṭhaṃ, indriyānaṃ adhipatiyaṭṭhaṃ,

It prevents knowing the meaning of heap in the aggregates, the meaning of actuating in the sense-bases, the meaning of voidness in the elements, the meaning of predominance in the faculties, and the meaning of suchness in the truths, thus it is called ‘ignorance’.
