The reason being the MOPH has this intention (see attached infographic) and also, July 1 is the target date for "endemic" status. Of course it's too early to say for sure whether this will happen, but it's still likely. Just today the Covid alert level has been downgraded to level 3 from level 4 and in recent days the government has repeatedly said that July 1 is still on track for endemic status.
In other words, I believe there will still be some restrictions in place during June (though fewer than this month) but it could well be that things will be back to normal by July 1, rather than end of July.
