Pci-e link speed (Asus B450-Plus gaming)

I’m considering the Asus TUF Asus B450-Plus for my Ryzen build with a 2700x

on the spec page, it says

AMD Ryzen™ 2nd Generation/ Ryzen™ 1st Generation Processors
1 x PCIe 3.0/2.0 x16 (x16 mode) 
AMD Ryzen™ with Radeon™ Vega Graphics Processor
1 x PCIe 3.0/2.0 x16 (x8 mode) 
AMD B450 chipset
1 x PCIe 2.0 x16 (max at x4 mode) 
3 x PCIe 2.0 x1

does it means it has:
1 pci-e 3.0 16x slot (at 16x speed)
1 pci-e 2.0 16x slot (at 4x speed)

I am correct?

Yes, you are correct.

Going from top most slot down it would be

  1. PCIe 3.0 x16
  2. PCIe 2.0 x1
  3. PCIe 2.0 x4
  4. PCIe 2.0 x1
  5. PCIe 2.0 x1
