BGP Filters. Do not understand it strange behaviour

RouterOS Forwarding Protocols
1

Hi, guys!
I have iBgp between R1 and R2 routers (R1 - Mikrotik ROS7.6, R2 - Cisco IOS)

R1 announces 4 networks /24. They are described in ip/firewall/address-lists in one list, for example named AS65001.
10.0.10.0/24. 10.0.20.0/24, 10.0.30.0/24, 10.0.40.0/24

announce to R2 works well.

But! some subnets from this networks are in R2 physically.
So R2 announce back to R1 several /30 subnets. Same AS. For example:
10.0.10.112/30, 10.0.10.116/30, 10.0.10.120/30, 10.0.10.124/30.

On R1 I created filter to receive those subnets like this

if(afi ipv4 && dst in AS65001 && dst-len>24){accept} ← it doesn’t work

if(afi ipv4 && dst==10.0.10.0/24 && dst-len>24){accept} ← it doesn’t work too

if(afi ipv4 && dst in 10.0.10.0/24 && dst-len>24){accept} ← it works!!!

How can I make this filter more abstract, to use address-lists and to not strict define expected network(s)?

“dst in address-list” means that it will check if destination is in address list (exact match)
“dst==10.0.10.0/24 && dst-len>24” - does not make sense, destination cannot be equal to 10.0.10.0/24 and at the same time have netmask larger than 24

last example is the correct one
