30 day pass help please

[Jflower101]

Good morning everyone,
I wondered if someone could help please?
I am arriving in Singapore on Friday 23rd (tomorrow); I am a UK passport holder and will get the 30 day on arrival pass. I used to live in Singapore so I am visiting friends and will return to where I live in Bali on Tuesday.
My friends want to do an overnight trip to Malacca in Malaysia on Saturday.
My question is; is it fine for me to obtain the 30 day pass on arrival on Friday, leave on Saturday, get another 30 day pass on Sunday and exit finally on Tuesday?
When I lived previously in Singapore I had an employment pass so did not need to worry about these things.
I have a valid passport which will not expire for years, proof when I am leaving Singapore again etc.
My concern is if the land border control are fine with me re-entering on the Sunday? We will cross the Singapore-Malaysian border on Saturday and Sunday.
Thank you in advance for your help. Sorry if it is a silly question it's just important for me to be in Singapore on the Monday for a special occasion!
Thank you.
